Hi all.
I have read many posts about different experiences and possible issues with hard drive. IMHO & from personal experience of using HDD in Smartphone etc..it is best to install ALL programs to either device memory or SD card. Use your MD solely for data storage and media (photos, movies and Music).
Personally, I would, like wu, install all GPS software to SD card, as it will ensure that the shock resistant technology won't even be needed for sensitive programs.
The HDD is a mechanical device peeps, it will inevitably put more of a strain on the battery.
Simple test for all you owners of the Athena:
1) Choose any movie and transfer a copy to your SD card and a copy to the Micro Drive.
2)Ensure your battery is fully charged at the mains then disconnect the mains and use TCPMP to bench-test the entire movie from MD....look at media properties afterwards and take a snapshot of all the details or note it down....now check battery consumption.
3) Recharge battery to max again and repeat the process using the SD card and record the results.
If you find the MD is performing better (I'd be happily surprised) then technology has moved on considerably in the last few months. If however SD card is performing better, power consumption wise, then you know for sure which will last you longer.
Whatever the result is I will still be setting my Ameo (when I get it ) as stated above, but it would be interesting to see from TCPMP what speeds the movie is benched at from both storage mediums.

I agress, that is a good way to test it. I have broken my SD card so i can't test it now, but personally i will install all the programs and navigation software on SD, and move the music, movie file to MD.
However i should let you guys also know, i have tested the writting and reading speed between these two using Pocket_Mechanic PRO, and the MD result is much higher than sd for some reason....

Interesting Wu. seems like MD hardware has made significant improvements.
My biggest concern is that if I install to MD and it by chance fails, I will have lost everything, but to SD, I don't foresee major problems.
I think when I get my Ameo, I will do a full setup between Device memory & MD and do a full backup with Spb Backup to SD card.
Then hard reset and do a full set-up to device memory & SD card, also with a full backup to sd card.
Save both back-up files to PC, just in case.
Then give each method a trial run for a week to see which, if any yields better results.
Hope you get your new SD card soon. So is the Athena SDHC compatible then? I think I read one of your posts somewhere that you had to rename the SD card to 'Storage Card' and then all worked well. Is that right Wu? And what is the largest available SDHC card on the market right now? Is it 8Gb?
I hope so. That would effectively give us in excess of 15Gb of storage space. Woohoo.....that's almost comparable to the Sony UMPC with 16Gb in-built Flash memory!!
Makes one wonder what is truly possible to do with the Athena.....dual boot O/S's? WM6 & Linux (when they get it functioning as reliably as WM O/S's).
This all getting quite exciting....possibilities possibilities.

Yes i am very exciting as well, Athena has got lots of possibilities.
Anyway, i think SDHC still not function very well,, or it could just be my card is fake ! so i go for the sandisk ultra 2 GB this time (non SDHC). The one i bought before is transcend SDHC 4G. don't know is there any bigger one, but i will suggest all Athena here but the normal mini-sd now, and wait a bit until there are more choice for SDHC. i think it's not very stable at this moment either to do with card or rom or machine.

Thanks for that Wu. Standard SD card it is then. They come up to at least 4 GB since last year, so a bigger version is imminent if not already on the market.
Oh am I sorry to report that I am having serious issues with this Micro Drive of the Athena.
SD wins hands down for me...like MD is snails pace in comparison.

That may explain why I'm having problems then. Well I suppose it's not that negative after all then as it seems that the Ameo ROM may be suffering similar issues to the X7500 Rom. Still hope for the future then.

well, actually you want to avoid the same problem that the Advantage have right now, basically, if you take Advantage on the road, you are likely to damage some sector on the Micro Drive when you come back, that's their ROM problem, as you can see, it's quite a big issue, so that must fix it before they release it.
I don't think Ameo has the same problem, but it so, it's bad because until you update the Rom, you probably damage the Micro Drive already.....
.......right in the middle of a super demanding day, the message "damaged SD Card / Reformat" appeared on my Epic, when I least expected it (inopportune is the word)............ changing firmware is never without its more interesting moments, + this may or may not be a symptom (went froyo to gingerbread), however,........... am sharing this post to the Epic community, as i sense this to be an important enough issue...........no one really knows the specific cause of sd card corruption + failure: it's variable + always somewhat circumstantial (ie, saw it mentioned elsewhere that overheating from an overclocked cpu could cause damage as well)...................so, moving forward I simply want to contribute as a brief description, here, how i was able to recover (most) of the files from my 'damaged micro sd card:'
First, when i saw 'damaged sd card / format card' on the phone, when it became possible 4 me to do so many hours later, instead of 'formatting' I replaced the damaged card for a new one (pny 16gb sdhc class 10)...booted the phone everything was fine (15.91gb space available)........as expected, no files in the SD Card......................next:
(1) placed 'damaged' sd card into the reader that came w/ the device, and mounted to pc, selected the drive (followed by confirmation beep 'device detected' sound, then the language: 'd:\ not accessible. The file or directory is corrupted and unreadable' came on the screen..........went to RUN and typed CMD........from new window, I typed Chkdsk d: /r and the PC began reading the contents of the damaged SD card (most of the android zip files etcetera were there, as were a number of files w/ no content) + next i typed 'exit' (no quotations, just the letters) to return to the windows desktop.......OK, so now the only files missing are the pix + video mov's (far as I can remember).
..........(2) next, to recover pix + video, from the pc desktop i opened ZARecovery (if you do not already have it go to Data Recovery Software, Solutions, Tutorials, Forum - ZAR Data Recovery and download the free recovery program from that site).
.............(3) from the ZARrecovery main page, selected sd card as device, selected 'next', selected 'root' folder for all files that ZAR was able to detect as recoverable, entered destination folder name (for transfer of recovered pix + video to PC....note: NEVER to sd card itself!), + lastly, selected 'start copying selected files'.........and that was it, closed ZAR + began viewing the content of the recovery folder to get an assessment of what had actually been recovered, and what had been lost.................fortunately 4 me, the loss was minimal, as I tend to create backups (Nandroids, every half year; pic, videos, email attachments = pretty regularly).
Hope this helps those of you that have been experiencing microSD Card damage (from whatever source).
Remember, + not to speak to the Choir, but can not to overstate this: BACKUP............. BACKUP............. BACKUP.............BACKUP

Yikes! I make nandroids before I do anything I consider major like updating Superuser when the reviews are sketchy, or when I do something like apply a new patch, a new tweak, or anything that I think could give me trouble. As I have my phone tuned absolutely perfect, where I want to bring my phone back to normal with a minimum of work.
I guess I am lazy. I nandroid every 3 to 7 days.

I should add that one of the reason I nandroid so often, is that if I do it every 3 to 4 months (on my wife's epic because she travels) when she gets back, I have a ton of updates to catch up on - mine of course is always up to date.

I am so paranoid about sd crashes and corruption because I have had my share when upgrading to the next bigger card (had a 2,4,8,16, and now 32gb in each epic) that I sync my epic cards to my PC on two separate drives for both my wife and myself (my PC has three physical (not virtual)l hard drives C, D, E) every 3 to 4 weeks. So for her, I am pretty safe except for those long updates in between her trips home. I feel pretty safe in case I do something stupid, which I do from time to time.
I actually tried to convince her to get an iPhone, because I think there would be less updates than Android, but she won't give up the physical KB. Not that I don't like updates, but I set her epic to be a 98% clone of mine, so we each have a lot of apps and each app is eventually updated and often!

There is an undelete beta app on the market. Check it out.
Also, check out testdisk for when the partition table is fried.

Gr8 backup regimen..........'best practices' worthy.........given the 1,000 cumulative hrs leading to your perfect setup, worth all the special handling to keep devices singing!
props on the recovery
Mine took a dump today but it may be a total failure. I just got home and this is what the preliminary tests show. I would appreciate any input.
chkdsk
The type of the file system is RAW.
CHKDSK is not available for RAW drives.
testdisk
Capacity incorrectly showed at 8225kb/8032kb (16gb card)
Analyze feature reports a Partition Rear Error
As a sidenote, the TitaniumBackup sync-to-Dropbox feature has probably saved my butt as far as apps/data goes. I highly suggest using it to protect against dead cards.
Sadly SD cards and USB sticks are very unreliable when it comes to data. They are easily damage and anything slight can cause them to be corrupted.
This is a great guide, glad you were able to restore your data!
Most data in flash type memory cards (excepting physical cracks in the microSD Card housing + damage to the memory chip itself) can be recovered w/ several DIY software programs available on the android market..........ugothkd shared a few of these, several posts up.........in the event that there is NO BACKUP available to you + having exhausted all personal DIY recovery avenues, there are still ways to step-up the process and very likely recover some of your data..........am quoting the following language from Recoverfab (maker of enterprise flash readers to the trade):
'In general, there are two reasons why the data on memory flash devices (cards, USB-sticks, SSD) becomes inaccessible.
Logical damage prevents access to the data/pictures on the drive, but the drive is still physically recognized by the computer operating system. In this case some specialized types of recovery software can help. Sometimes free recovery tools like Zero Assumption Recovery can also solve this problem.
Physical damage causes the drive to be unrecognized by the computer's operating system, making it impossible to access the contents of the flash-memory chip. This type of damage happens in more than 80% of all known cases. These are most frequently caused by electrical problems that lead to physical damage. Flash devices consist of a memory chip and a controller. The controller writes and reads the data from the memory chip. In most cases, recovery is possible from a flash device with a damaged controller and mostly undamaged memory chips.
Formatting is required? The controller of the memory card is not in the position to inform the PC operating system about the characteristics of the memory card. Therefore, the PC assumes that the memory card is not formatted and requests formatting. One might think that the memory card problems would be solved by formatting, but unfortunately it does not work due to the damaged controller. Instead, the computer will communicate that formatting is not possible. Such an error is a clear indicator that no kind of software (including special formatting or rescue software!!) will be able to access the memory card.
.....Recovery Process: If the flash storage device is not recognized in the computer or it is impossible to access the data on it, there is only one way to get the data: unsolder the memory chip from the printed circuit board and directly access the raw data with a programmable chip reader.' <end quote>
OK......that was a long quote!.....worth repeating, if only to begin to address the sort of things that can damage / corrupt SD Cards (+ also to give those of you that really want to recover your lost data super badly some HOPE).
Heat, liquid, dust, some of the things that WILL damage your SD Card (numerous other things can corrupt your data as well) .....then you hear cases of individuals that have NEVER HAD ANY DAMAGE WHATSOEVER...........some burnin' Q's: is the fragile nature of the card itself doomed to failure? ...If the card is going to fail eventually, what kind of data would you be willing to risk storing in there?...... if the data is that important to you, would you be willing to make a 'twin' copy? (twin SD Card could be swapped quickly in case of ER) ..... + lastly, has anyone here found a fail-safe or fairly sound way to run voluminous or frequent data transfers between your device's SD Card + pc?

Yup, I have a spare twin identical card Lexar 32gb class 10 waiting in the wings as a backup.
I use a program that can transfer and/or sync in many different ways my card to my PC, which I do every three or four weeks. It is called FolderMatch v3.44. I am sure there is a newer version out, but the one I have does the job
I simply plug my USB cable into my PC and the other end into my epic and simply choose synchronize, then chose make left folder (my PC) to be the same as the right folder (my epic) - depending on how many files you are syncing determines the speed of the sync. Works good for me!

ZAR has an 'unformat' option for Raw File Systems, you may want to explore if there is data remaining in your SD Card that you may want to recover (there's a brief tutorial posted on their website) ........ here's a glimpse:
"Unformat is the process of data recovery from a storage device (which can be a hard drive, a camera memory card, an USB pen drive) that was formatted.
The step-by-step tutorial below describes the procedure to recover data when the drive was accidentally formatted and you want to unformat the drive Windows reports "raw filesystem", or the drive is "not formatted" <end quote>
The above makes reference to a specific type of recovery (accidental format of a drive, as an example), but the application will recover from a number of file types + systems............worth checking it out.
*edit* as another example, 'accidental format of a drive' can also refer to split-second decisions we make when we guickly hit 'reformat sd card' on our device the very first time we ever encounter a 'corrupted external card / reformat?' type of message........in the moment, life goes on + it's only later that we begin to think of the lost data..................however, chances are pretty good that the data is recoverable (files are still inside the 'reformatted' sd card, only unreadable, ie RAW).
Hello Folks!
I guess my question will make me sound dumber than a box of rocks, but here goes. A bit of history before I make myself an idiot. I've only been fooling with computers and these new tech. machines for about a year and a half now and for the most part been having an enjoyable time. I'm 70 years old and I'm not the sharpest crayon in the box anymore, time has dulled my tip a bit. I've been given a Nook Tablet as a Christmas gift by 2 of my grandsons, I intend to change the Android on it to the Ice Cream version but before I do I want to practice on something else first. So I bought a used Nook Color from a lady at church for $50 and I want to try and make a SD card to run the new Android from. The reason I want to use SD card is that there are over 200 books on the Nook and I would like to eventually read a lot of them. I guess I'm just greedy.
I've spent most of the weekend reading this forum information, but unfortunately the more I read the more confused I get. There is a tremendous amount of information to try and digest here and sometimes some of it seems to contradict itself. What are the different types of modified Androids that can be used? Can the Andriod that is installed on the SD card be modified so that more applications can be stored on it? How difficult is it to install the software that allows you to speed up the Nooks processor, that is, can a raw noob do it?
I'm sorry if I've yacked too much. I'm still learning how to correctly ask the questions.
Hey, knock off the old man stuff. I am 67 and my crayon tip is still sharp (although there are some here that would disagree with that, LOL). This nook color stuff is not that hard. I would recommend putting cm7 on sd first to get your feet wet. Then if you feel like experimenting move on to cm9. You can get the rom at cyanogenmod.com (for the encore - Nook Color). I recommend 7.2 RC3. It comes already rooted and overclocked so you can speed it up. And it has plenty of room for apps if you put it on a 4Gb card or larger. If you can afford it, I recommend 16GB (and Sandisk, class 4). Follow this guide to set it up:
http://forum.xda-developers.com/showthread.php?p=12240928
But look at my tips thread linked in my signature to get an updated image to use instead of the one in the thread above. Also read all of section B in my tips, as it all applies to the sd installation. If you need more help, just come back here.

And in keeping with the older guy thread concept (66), you're talking about two different devices, the Nook Tablet (NT) and the Nook Color (NC). The newer NT is much more difficult to deal with than the older NC. It's not as straightforward to install anything on the NT as it is for the NC. Also try to differentiate between the device hardware and the operating system software. The software will get the most out of a particular devices' hardware. The NC's processor is single core; the NT is dual core. The Ice Cream Sandwich (ICS) Android operating system applications are pretty much the same between the two devices, but the operating system interface between the applications and the hardware (the kernel) is different, so overclocking, over/undervolting, etc. will be different, too.
Just keep reading; that's how to sharpen the tip. It's never permanently dull until everything else is.

You're right of course. I was talking about how to update his NC. I also have an NT and it is much more difficult to deal with on modding.
Actually, after playing with the rooted 1.4.2 stock NT, I see no reason to move to CM yet on it (BT is the only thing missing on stock), even though I have CM7/CM9 on dual boot SD. After CM gets more stable on the NT, maybe.

Gentlemen,
Thanks for the replies. I don't feel old most of the time, just when I have some of the youngsters whizzing past me. Computers, smart cell phones, and Nooks are fairly new to me, never touched one until after my wife passed a year and a half ago. Now I need one to keep in touch with my family (4 kids, 12 grandkids(and 3 more on the way), and 4 greatgrand kids (and 2 more coming).
Due to a accident last fall the old brain sometimes has a bit of a hard time comprehending things now and then, so I get a bit frustrated and I may ask questions that seem to be a repeat. Hope you all can forgive that.
Thanks!
The tablet my grandsons gave me is a Lenovo A1 not a Nook tablet. It is running Android 2.3 and I want to upgrade to Ice Cream Sandwich when I'm confident enough in my abilities.
Well done, gentlemen.
These two will have you building your own Android OS before you're done, GrampaBear.

There's very little activity for this device on xdadevelopers, and what we know is primarily for the Nook Color.
Well, I started the process of making an SD card with Android on it. I am now thoroughly convinced I am near as dumb as a box of rocks. I download the agnostic sd card image and the win32imager. I didn't realise I needed to uncompress the files ( this was a first for me, never had to do it before ). I finally figured out I needed WinZip and I downloaded the trial version and ran the program. I took a old Kingston 4 GB class4 micro sd card (I have ordered a Sandisk from newegg but didn't want to wait to try) and formatted it to fat32 with a sd formatting program. I then ran Winimage (with my fingers crossed for I was not sure of what I was doing) and I think I have the image on the sd card, at least when I look at the card it windows it says boot on the sd icon. I went to the site where the C7 images are kept, but could not get one to download ( this was around 11 pm last night ). One problem I have is that I have no idea what I'm looking for when I pick a file. Could you tell me which one I should be using? It says I should write the image to the card, put the card in the nook and boot it. OK! I'll give that a shot, but how exactly do I get the Nook to boot off the sd card and how exactly does the Nook know what to do with the program? Will this mess up the Nook and the programs on it?
I knew that this would be a project, but after 12 hours of reading and trying I've become a bit frustrated. Maybe someone would take on a project and write a forum called The Big Dummy's Guide to Installing CM7 to a SD card and do a step by step instruction that tells us dummys what we should be seeing as we do this.
Funny you should ask about the dummies guide to SD installs. Taosaur just gave me a link to his here:
http://taosaur.blogspot.com/2011/09/running-cyanogenmod-7-from-sd-nook.html
He gives links for the CM7 files. Pick the CM 7.2 RC3.
Once you get the SD set up right and the CM zip on it, just put in your nook and boot. Everything is automatic and does not harm your stock install at all.

Thanks for answering my post. Looks like I'll be starting all over with the process again later this evening. You must have been doing this work for quite a while with the knowledge you have.
Well, for now I'm taking my 6 1/2 year old great-granddaughter, a couple of fishin poles, a can of worms, and we're walking down to the pond to catch us some bluegills for dinner. Need to have a little grandpa fun and let the ole brain relax for a bit.

Leapinlar's post will answer your questions, but here's a few things to watch for that may concern you:
1. It takes a while for the initial install, and you may see a black screen without any indication of activity. Don't panic! If it lasts more than 20 minutes or so, turn the Nook off, pull the sdcard out, and start again. Don't be afraid to redo everything.
2. The first time it successfully boots into Android, you will see the introductory splash screen for what seems an inordinately long time. It's setting up files and processes so just let it run. Once again, if it takes more that 20 minutes or so, there's most likely some problem.
2. The Kingston card may be sloooow, so my comment above is even more possible. Because the Kingston card is so slow, when you finally boot into Android on it, you may think that the system is too slow or error-prone to run on an sdcard. You may get popups during boot up, when you're running programs, or when its just sitting there, saying something to the effect that so and so program has a problem or had a fault or whatever, and asking you to wait or "force close" (FC). This is probably caused by the card. Your Sandisk card will generally not have those problems (I've been running for over a year on an 8gb Sandisk card with no problems and very snappy response).
Thank you
Shumash,
Thank you for the information. I tried my first try at making a card tonight, it appears to be a no go. Left the Nook alone for an hour and 15 minutes with nothing apparently happening. I will reformat the card and try again tomorrow. I want to thank all who have written to help me along. I know what a pain in the kester having to work with absolute beginners can be.

I see you used winimage to burn. Do not use 'write disk' to burn it. Use 'Restore Virtual Disk Image to physical drive' in the same menu. That's why I recommended win32diskimager. It is simpler to use for noobs.

Shumash,
I did use win32diskimager but I apparently did something wrongin the process. I will try again tomorrow it's late and I'm a bit tired.One thing that I will be doing also is trying to learn as much about Android as I can, though it may need to be in a bit simplified format. If anyone can suggest available information this old geezer will appreciate any guides to it.
I finally did it!
It took me 6 trys and I'm not sure what I did right this time, but I finally had success. The first 5 trys all I would get on the screen were 3 lines going across the screen about 40% of the way up and nothing else. The last time it booted and took a bit of time probably 12 - 15 minutes working and then shut itself down. I was thinking it was another failure and held the power button down for a few seconds to restart and Bingo! up came the Android window. I messed around a bit and set up the wireless and pulled up the internet. I LIKE IT!!
It is a bit slow and I'm assuming the Sandisk card will fix that when it finally arrives. It didn't freeze up or anything just ran a bit slow. The Lenovo A1 that my grandsons gave me is always locking up.
The only other thing that I have a worry about is the micro sd card reader in the Nook. I did have a pretty hard time getting the card in and out of the reader slot. I've labored with my hands all of my life and I have developed rather thick and calloused fingers and a bit of arthritis doesn't help either. I can not physically fit the tip of my finger into the little open loop area for the SD card reader. I had to use a tweezer from my fly tying kit to insert and remove the card from the Nook. After I get this type of card down pat I'd like to see if there is a way to leave the card in all of the time and be able to boot from the card or the nook reader software.
THANKS AGAIN! I wouldn't have succeeded without all of you gentlemens help.
While I was finishing typing this message my 13 year old grandson has been fooling around with the Android on the Nook. He said to tell you, that you all are AWESOME!

If you're using windiskimager, getting everything straight can be a bit confusing. Make sure that you're doing the following four steps on your PC, not the Nook!
1. To the right of the box that says "Image File", there is a blue folder picture. Click on it and select the image file. It should be something like "generic-sdcard.img". It's easiest if the image file is in the same directory/folder as the win32diskimager software.
2. To the right of the blue folder looking picture is the selection box for the location where this image will be written. It says "Device" right above it. If it is the wrong drive letter, click on the arrow at the right of the box. Select the letter of the sdcard. Use a file manager or windows explorer to find out which drive letter the sdcard is. Make absolutely sure you know which drive it is!
3. After you have properly selected the image file and the correct drive letter, click "write" and wait for it to complete.
4. After the image has been written, you will have to put the CM7 (Gingerbread) or CM9 (ICS) flashable zip on the sdcard in its root directory (called "/boot" in a file manager or windows explorer). Copy the one you want onto the sdcard.
Once the above is done, remove the sdcard from the PC and put it in your Nook. Boot the Nook up, and it will do everything else automatically.

It's funny you should mention old hands and micro chips. I have always had a hard time with the chip and that darned slot. Yesterday I was changing the chip and it popped out. I was sitting in my big recliner, you know the kind all old folks have, LOL. Anyway, the chip went down the crack in the chair. I could not find it. I finally turned the chair on it's side and shook it. It came tumbling out. LOL.
So you will be glad to hear there is a way to set up your stock so that you can use the same SDcard. The only complication is your stock must be rooted first. But that is simple to do. But maybe you want wait on that till you are more confident. Once it is rooted you can look at my tips thread, item B3, and I tell you how to set up stock to use the same SD so you don't have to keep changing cards. There is another method of setting it up without rooting first, but it is more complex to do. If you want me to reference that thread, let me know.
Leapinlar,
I know what you mean about the old folks and recliner thing. I have a big old style chair with a foot stool that my wife bought me at a garage sale 38 years ago. It was well over 20 years old when she bought it. She re-upholstered it and made it into the most comfortable chair for a large man ever. I'm kinda like Archie Bunker with that chair, it's my chair and you don't sit in it unless I offer it to you.
I appreciate all the help you all have given me, this is all new to me and sometimes I get to feeling a bit flumoxed. I'm having a bit of a problem getting the Android gapps program to work at the moment. Think I may be copying it to the wrong spot, but Windows only seems to show me one spot to copy to. I'll get it figured out it'll just take time. It may be a bit before I feel brave enough to root the Nook.
Still waiting for the Sandisk card to arrive. The Kingston card seems to work but is really slow at times.
You're copying it right. As you turn the nook on with the card in the slot, hold down the n key and choose to boot into the SD recovery partition.

Hi,
It's the 2nd time that my SDcard stops working. Overall using SDcards on my SGS3 and now SGS4 - I have lost 4 cards (in a period of 1.5 years).
I am making sure that I am buying a Class-10 cards and they are usuaully 16Gb or 32Gb (the one that I've just lost is a Polaroid 16Gb class-10 - not the cheapest one).
What I see right now is that some folders has files that seems to be corrupted. For example DCIM folder has a file that looks like uAMERA (instead of CAMERA) and its at a size of 0b (this is a folder obviously and I cannot modify that name anymore).
All the files under the Titanium backup has weird names now.
My questions are:
1. Is there any type of tool (something like an 'fsck', etc.) that can actually try to recover whatever got corrupted on this card?
2. Is there any recommendation, anyone who had a good experience using an SDcard over 6 months or so, What should I buy as the next SDcard?
3. Is there an application that will check the SDcard 'health' and will, hopefully alert, that something is starting to get wrong with the SDcard? (not sure if that is even possible).
Thanks,
Gil.
Positive experiences using Samsung class 10 cards. Used a 32GB-version for over two years in my SGS2 and now a 64GB one in the SGS4, all without any problems whatsoever :good:
Get Samsung microsd card. Been using it since I got my S4 and no problems so far.
After i had a few cheap memory cards fall apart, i now only buy Samsung as they are very durable, see below.
Samsung Memory cards can endure 24 hours submerged in water and survive being run over by a 1.6 ton vehicle (SDHC, SDXC), not to mention the perils of airport x-ray machines, magnetism and extreme temperatures.

I can recommend you an ADATA micro SD cards (as well as SD cards). It`s got great performance, stability and price. Now i`ve got my third one which is 32GB ADATA mSD card with 28Mb/s read and 18Mb/s write. (five or lifetime warranty depends on country)
I recommend Samsung microsd! I never had problems with my 32 GB microsd

I've had 2 issues with my SanDisk 32GB Class 10.
First time it stopped mounting and kept trying to "repair itself." Brought it to pc.. the card had all my files but it was super laggy. I couldn't access anything, even though the files were there. I ended up formatting. Worked afterwards.
Second issue was it un-mounting and showing blank or unsupported files.. I was watching an episode of The Simpsons, the next file I opened was a Family Guy episode.. that's when it decided to stopped working. Restarting phone didn't work so I shut down and removed the sd card.. worked after reinserting.
None of my files were corrupted/virus
But so far..its working. Good thing I sync with Dropbox.. would have lost all my pictures and video's..
I'm using Transcend MicroSDXC 64GB UHS-I. At first i got bad memory, the card stop working or got error after copying 31GB of data or if i format the memory (non-quick format) it will give error after 51%.
After replacing the card, it looks ok now.
My G S4 just did the same thing... uAmera or the microAmera folder... All photos are gone. Tried recovering with no luck so far. Anyone else experience this?
Hello to all , i have a very strange problems about my Samsung Galaxy Note 4 ‘ s ( you will understand why i said like this instead of note 4 ) and with my Sandisk 32 GB Class 10 U-I micro-SD card , first of all i want to tell that , I were using this card with my old galaxy Note II (GT-N7100) since 2 years without having an issue or problem ( with all my musics and pictures inside the sd card and also almost my all programs were installed on sd card , while sometimes my Galaxy N II was in stock or custom rom , there were no any problem) , anyway , then i decided to upgrade to note 4 so , i bought 2 Note 4’s from a company in Cyprus (Models: SM-N910H and never opened box ) , 1 is for me (black) and 1 is for my wife (white) , anyway , i just opened boxes and setup phones and restores our backups (as you know contacts, sms and some programs that i already used on Note2 throu Google play) for me and for my wife ,(beside,but before i just takeout my SD card from note 2 and make o quick format on PC with a exFAT file system which is my note 2 was working great already with exFAT before and also FAT32 as well, then put it to my new Note 4 as new Formatted ) after a while (few days later) My note 4 start to pops up sudenly an SD card error "SD card is blank or has unsupported file system “ and when i touch it Format disk pops up and when i click yes it says checking the disk... and trying to format but does not format the disk and same error keeps again like SD card Blank ...... bla .. bla .. so i take out SD card from My note 4 and put to PC but no any problem , all my files at there , even i checkdisk the SD card but has not found any problem , then i put SD card to my old Note II again , even i can access files and has no any problem again , then i just put the card to my wife note 4 and also it detected card and it was working , after , i just format the SD card on my wife note 4 (whats an interesting point is that , my note 4 does not accept to format the SD card but my wife Note 4 formatted and successfully mounted the SD card without a problem) and i put it back to my note 4 again , and it was mounted succesfully , so started to setup again buy copying musics , puctures on to SD and install programs again to sd by using the application manager as for some compitable programs with “move to SD card” options , so i used my note 4 2 days with no problem then , i shut down my N4 at 2nd day night and put it into wall charge while it was powered off and when i wake in the morning and, i switch on my N4 and again my programs short cuts get dark (programs lost , and my musics plays first 4 – 8 seconds and N4 music player try to play next track like this loop then when i try to format disk again on my N4 , it did not format the SD and give SD card error "SD card is blank or has unsupported file system “ again then i put to PC but no any problem again , so i think that my N4 card slot is defective and give back to company where i bought it and request a replace but they dont accept they said they will test it about 10 days , so they said they tested it and the problem is about on sd card , because of under the SD card there were a black sticker which i was removed it 2 years before (also after i removed the sticker it was already working with my old N2 without a problem), and they said they fixed it by sticking to the under of SD card a white sticker (which is shown on picture) , so i get my N4 and tested 2 days worked great with SD card but when i shut it down and put it to charge when i wake up next day (3rd day) the same problem happened again so , ı went the company back for an replace but they said they will not replace but they would refund me with in max 10 day , anyway i left the N4 and start to use my N2 again with the SD card and it did not occured any problem and at the end of 10 th day , i got my %100 refunded money back , while in this period i did some research and learn that SM-N910H model only 3G variant and will never support 4G , so due to my research i decide to buy SM-N910C or SM-N910CQ or SM-N910U , for an 8 cores with 4G support , by a luck , i found on an other small company just one SM-N910CQ model which is an Turkey product and the box never opened before , and i told the seller i want to open box and test it here before buying it , she said ok , and when i just open the box , i put out the sd card from my N2 and put to it and first run it and then BOOM again it gave the same error again , so i left the unit at there and did not bought it the seller said me that your SD might damaged , then i said her , ok put it you personal phone , which it was galaxy S3 , and she put and test it , the sd card were working and she agreed with me SM-N910CQ might be defective (please note that the SM-N910CQ came from the first company that I bought the SM-N910H unit , which was the company name were SUITEX LTD.) , and I started to think that all the series that , SUITEX LTD. NOTE4 S are defective or damaged , finally on last other company , I found my monster again SM-N910U (the most prefered model prefered by me cat6 4G and an upgraded Mali 760) nand it was last un-opened box , but when i opend box , and tested the card , it worked , and i immediately bought it , i were heppy i setup all the things and used it 4 days without any problems , and guess that what happend in 5 th , when i wake in the morning and turn the phone on again my programs short cuts get dark and then i click them they are not working (which i moved to SD card) and then i try to format the disk from my N4 it try to format but it can not , then gave the same error loop again like "SD card is blank or has unsupported file system “ but after 1 or 2 hour it fixs it self and , and all works as normally , so experts please help me , what might be the problem ?? , i am sure %100 that all the N4 were ok , i can not be unluky like that 3 Different model of N4 from different company can not be defective at the same tame , also i %100 sure that my sd card also ok , because its working with my Destop , Laptop , Note2 , and on my wife Note4 like a charm , also when i test the SD card , PC’s does not find any problem , i also Low level format My sd disk and make surface test , unfortunately not found any problem , I also formatted my SD card with SDFormatter4 which is provided by sandisk , and it has no errors again , also , i checked the compability of my 32 gb sandisk over the sandisk site , but it says %100 compitable with Samsung Galaxy Note 4 , i searched google and forums but not found any solution , so please help me what the problem might be ?? it can be related about note 4 software bug ?? maybe something wrong about android 4.4.4 ?? , any user like me ?? like this problem ?? please help , sorry for my bad english

There is many posts on xda about sandisk cards failing in samsung phones. I dont think anyone has definite answer what is the problem. For some cards work for years, for others failing quickly. It appears that samsung cards dont fail when used in samsung phones. Is that coincidence?

My suggestion would be to connect the SD card to your PC and copy all your files in a safe location. Then buy a new SD card, preferably a Samsung one, from a reputable seller (as to avoid fakes) and copy your files back to it. That way, even if it has issues, you'll be able to exchange the card or get a refund. It should be much easier than getting new phones.

Dear darekz ,thanks for your answer but , did you read my post completely ?? as i mentioned there , i used that disk with in many samsung phones without having a even simple problem , but this disk makes problem only with Note 4 's and i think that to say "this model of sandisk has an bug with Note 4 with the current software at least (android 4.4.4) " is more logical , beside i did not see any post that sandisk is not compitable or fail with on samsung phones do you have a link ?? , can u sahre with me a few ?? , and also in my opinion samsung note 4 software development team must fix this bug with software updates , even this problem may will be fixed on lolipop update ?? , what you think ,

thanks for your answer but , to say put it out and buy new one is easy , we must try fo find a solution , or, we must make N4 software team to fix that bug immidiately at least , i bet that lots of people that using N4 have problem with SD disk but they even unaware of it due to music or pictures only inside on sd card (not software installed) , so i advise them to test the sd card with N4 by shutting the note4 off (power off) and after a few minutes , let power on phone and enter the file manager of N4 and let explore and check the integrity of the files of the SD card that correct or not (if the all files on SD card or not) then please wrıte the results here , , i bet lots of people will say that my files are missing , because i belive it is a Note 4 software bug so i advise all please test your N4 with SD card and verify that if is working or not and write the model no as well , especially Exynos user
so , if we sum all of it , I think that this problem is a general problem and its a bug between with Note 4 s and SD cards , please all note 4 user test your SD card if you have and write the results here with the model of SD card and phone as well by including OS build Thanks for all

I understand what you're saying and I agree that a solution has to be given by Samsung, if possible.
However, even if they do acknowledge an issue -which is doubtful, since most SD cards work fine- they need to find out whether it is something they can issue a software fix for and, if so, integrate it in an update some time in the future.
All I am saying is that it is going to be a lengthy process, if done at all.
So while you are right to be frustrated with this issue, the only immediate solution to it is to get a new SD card.
Good luck whatever you choose to do!

Dear iridaki & darekz
Thanks for your quick replys but what is a interesting point is that , now i am using my 32 GB sandisk as an flash disk with an Usb adapter on pc without a problem , also i am using my old Sandisk which it is 8 GB and even its class 4 with my note 4 without having a problem as well but, unfortunately the 8 GB is not enough for me and now , i am affraid to buy an new SD card that if the problem happens again , because as i mentioned before i could not evaluate that what caused this problem with my note 4 , also i am not sure that the issue because of sandisk , because my old 8 gb is also an sandisk and works perfectly without problem since 3 days , may be the problem is about classes of SD cards , because the 32 gb one was a class 10 card , the other one is class 4 , so anyway , i want to buy a new card which one you advise ?? i want 64 GB also if you have an card that just you are using with yours N4 without a problem please advise me , thank you

I have a similar issue but mine is that some files are getting corrupt (mostly pics and videos) even after many formats through pc. I have a 128gb Samsung sd card so it can't be compatibility issues. Maybe something wrong with the sd card reader on the N4. Can't find a solution yet. :/

lol my friend , you are absolutely right if you read my thread from the begining to the end , the problem is neigther N4 's nor sd Cards , and its a compability issues with SD card and the N4 reader on Android 4.4.4,even i rooted my N4 and installed ExTSDcard fix application from google play but it did not fixed the problem, but i did not test on lolipop (i never updated to lolipop) , only the solution that i found , i am only running an 8 GB MicroSD card (class 2 and Sandisk) about 20 days without having a problem for now , i think samsung may apply a update soon to fix this issue

Nope. Nothing new on lollipop. Already updated and I'm having the same issue. :/ Gonna try the Samsung card on another phone and another card on the N4.
So.. You have no problems with a class 2 card? Maybe it's something with class 10 sd cards.

Yes , i confirm that I have no problem with my N4 and old 8 GB sandisk card , no more any corrupted files and missing aplications (which are installed and moved to External SD card) but it is such a slow card if you compared it with a class 10 card and sometimes applications that installed on ExSDcard, the application logos get dark (like missing shortcut) on first boot for an about 2-5 second , then it became normal logos after 5 sec (i think this is because of the speed of SD card that which is class 2 , and when you turn off the phone , and turn on the phone again or restart the phone , it takes some time to mount the slow SD card volume again for prepare a usuage ) so this is acceptable and data integrities are ok but the problem is that the class 2 too slow for a Note 4 and i never seen an SD card as class 2 with High capacity like 32-64- or 128 GB , and i am also agreed with you and sure that its a speed related (class speeds) issiues that samsung must fix it immidiately with a firmware or with an small patch update

Yep. Surely is something with class 10 and maybe more. Sadly there are no high capacity class 2-4 sd cards, and they are very slow compared to class 10. I have lots of data so I can't put it on a low-medium capadity card. For now I can only save all in my pc.
I have a 64 GB UHS-1 Sandisk that fail after 1 year of usage.
Many confirmation of defective batch of Sandisk microSD especially with large size (64GB & above).
Sandisk even confirm this problem & offers free replacement.
It may be out there but I never read about 32GB failing except for this one.
But I can recommend Samsung EVO 64GB UHS-1 as it works perfectly & I bought 2 of it
You can quickly solve this problem by buying Samsung EVO UHS-1 or you can wait for Samsung / Sandisk solve this which probably takes years or may be even ignored as the problems is minor to their statistics.
Something to remember regarding using microSD in Android:
If you install apps into extSdCard, it may take longer to initialized after Booting.
While waiting to mount your microSD, all installed apps that located in the extSdCard will be broken.
The waiting time varies depending how many apps is in the extSdCard.
On my Note 10.1 (GT-N8000), I have to wait for almost 2 minutes before everything is initialized properly (I have almost 500 apps & many of it is in extSdCard).
On my Note 4, only a few seconds (fewer apps & faster CPU).
Widget apps won't be working if you move it to extSdCard
KitKat (and may be Lollipop) has SD card restriction that can break many apps.
microSD is using SSD technology therefore there is Write limit.
If the Write Limit was reached, you can only read your data, but can't write/modify/create.
It means, you can open documents, listen music files or watching video files in it, but if the limit is reached you can't delete/edit any of it. You can't even create a new file/folder.
In my failing Sandisk UHS-1 64GB microSD it shows all symptoms.
Moving many apps into your microSD, MAY increase the WRITE activities in your microSD & resulting in decreasing it lifespan.

My friend , thanks for your quick reply and yours helpfull informations but, can you explain me some of the points that then WHY ??
1 - Even there is some a few users that they have Samsung SD card and they use it with Note4 and some of have even have same symtoms like mine ? (please note that N4 and Sd card are not fake and i have a few links if required , i can post it ) ?
2 - If my Sandisk UHS-1 32GB microSD damaged or not stable , then why it is working with my old Note 2 - S3 -S4-PC or even on a other Android devices even without having a single problem then ??
3 - If Sandisk cards is not suitable or not recommended by Note 4 s or for Samsung then why My old 8GB sandisk (class 2) worked about since 3 years on my note 2 whitout having a single problem , or it is still working on with my Note 4 ??
4 - is' nt it so dictatorial that Samsung N4 series wil allow only Samsung brand SD cards ?? , but i think that it is a Generic MicroSD card slot , but if not so , samsung might supply a user manual with the phone that like; this brand and this ..... is compatible with the SD card slot , were a better idea (like a some of PC motherboards that some of mension that which brands are verified or %100 compitable for RAM modules) , because there are most of other brands of SD cards that also in good quality lilke Patriot, A-DATA , Kingstone , and .... soo )
5 - Lets think about SSD technologies (that is the fastest and the best Hard disk or Storage solutions technology ever in now a days ) , they have some of IOPS high ratings (input/output per sec.) like 5 - 10 M and think about a windows OS pc that equipped with an SSD drive , then why it does not gives errors like a blue screen or fattal error like Disk I/O errors when you are using it on too many process at the same time ?? , even on my note 2 i remember that while i were listening mp3's i were playing a slot game and at the same time phone downloads an update for an application , and were installing it , and it was performed before too much times like this on before ?? (please note that all the operations were on SD card because , mp3 ' s were on SD , the game that i played were also on sd card , and the updated application were also on SD card , none of them were not on phone main memory )
finally , i still belive that it is an sd card compability bug with Note 4 , and samsung must solve it ASAP with a firmware update or patch
There is no doubt that there are some product defects are out there from any manufacturer including Sandisk & Samsung.
In statistical science there will be around 0.5% -5% margin of errors in any mass productions.
So if Samsung/Sandisk produce 10 millions of products there are around 50,000 - 500,000 defects.
Of course they will try to reduce the margin of errors as low as possible by Quality Control.
The thing is QC is only taking random samples, therefore the possibilities of defect out in the market is still there.
Thus either Sandisk/Samsung will have "a few" defects in their products.
By this, I clearly stating that I'm not saying that Sandisk is bad & Samsung is better.
It's just some of Sandisk product batch in "large size (64 GB & up...+ probably 32GB too) microSD" is bad.
And from my knowledge, Apple iPhone 6+ 128GB is also suffering a problem with their SSD chip, so it's not only Sandisk & Samsung.
And remember that XDHC SSD tech in microSD is relatively new tech, thus glitches is expected.
"Many" is relative, 100 complain is plenty if the the total products is 110.
10,000 is a few if the total products is 5,000,000 as it less than 1% & usually manufacturer "ignoring" this case as it's only a minor case.
They will focus more on creating a new & better product than fixing the "insignificant" defect.
The best thing a buyer like you & I can do is: claiming warranty & get a non-defect one (or another device).
Another question for you: is it working for opening files & deleting/creating files or only for opening files?
My failing 64GB Sandisk is still accessible but only for opening file.
If it is working for both opening & deleting files/folders then most likely the Note 4 product batch in your area store's is bad (in the 2% - 10% margin).
Look at point 1.
Look at point 1.
This question is OOT (Out Of Topic), but I'll give you an answer anyway.
SSD is not HDD.
In SSD tech. there is no moving parts = only Chip(s)
In HDD tech. there is moving parts = Disc platter + reading head.
SSD & HDD have a different lifespan.
SSD has a limited write cycle & HDD will wear out it's motor (for moving the Disc platter+reading head) over time.
BSoD/Blue Screen of Death in Ms Windows environment is caused by Hardware/Device driver malfunctions & not because doing multitasking.
The malfunction causes are varies widely from defect product(s) to end of lifespan.
The speed of SSD tech. is also varies depending on what tech. is use on the chip (YES SSD technologies is also varies).
Samsung is using OneNAND tech. & Sandisk is using mDOC tech. but not limited to only those 2 tech.
Android is basically a Linux OS & in Linux, running apps in RAM is the best practice.
So, it's likely that Android will try "pushing" running apps into RAM no matter where it's origin (either internal memory & microSD)
It only accessing Internal Memory/microSD if "needed".
I don't know how old are you or what is your knowledge background, but my best suggestion is try another microSD that uses different SSD tech. from Sandisk such as Samsung (or others).
Another suggestion is returning your Note 4 & try to buy from another Store in another area, because the nature of manufacturing that produce mass products in batch & distribute it also in batch thus if the batch is mostly a defect batch then it's highly chances most other unit is another defect one.
Hoping for a solution from the manufacturer for a problem is a way, but it's better doing something than waiting
By this I will not reply to this thread anymore, consider it CLOSED (no offense ) & GOOD LUCK :good:

Mr d4rkkn16ht I am 36 years old and i am working as a computer technician since i am 13 , and also i used too much mobile phones platforums with different OS (Symbian , bada , windows mobile , Ios , and android) since 1997 , even i dissasemmble some of and repaired some of them , also i developed some of applications for windows mobile platforms for especially version 5 as well , in addition to this , i never told you that SSD is an Hard Disk , I told that "SSD is an Latest and Fastest Hard disk Or Storage Technology for storage solutions now a days " so , ı mean that it is the best storage technology that it can not be so simple that while it read some of data , you can not write at the same time , or it can not be limited due to a single wire limitation , because the data send or recived from SSD digitally and both SSD and controllers (you can say it PC Sata port or Android microSD card slot) has an DSP on it (Digital signal processors) , and sure that i know the differences SSD and HDD , HDD has an Moving parts as you told like heads , Disk plug , spindle motor , and a IC card which has a conroller of DSP and a single ram that works as buffer memory , but on SSD There is/are Single or multiple NAND Flash Chips with one or two NAND flash chips controllers on it (most commonly using like SANDFORCE , INTEL) that is making a very fast comminication betwen INTERNAL NAND chips and connected enviroment (Like PC or it can be any device like android , IOS phones or what ever you called ) , SSD can be also like a PCI or PCI-E card (all in one IC) that can be connected by internally to a device , both Platforums (SSD,HDD) Delivers a storage Solutions , HDD ' s are High capacity , cheap and slow (due to moving parts) and can be affected easyli by shocks , and SSD 's are low capacity , expensive , but very fast and can affort shocks almost 10 times that traditional HDD,
so , you know now , who i am , and i am not sure that if you read my thread from the begining or not, that I replaced almost 3 Notes 4 in my region from differents company , just for only this MicroSD issues , i can not be unluky like that, 3 times from 3 different company i can not be buy the (%0,5 - %5) damaged units , and it is easier and more logical for me that to say samsung Note 4 MicroSD card slots have some bugs that must be fixed with certain SD cards brands or models , i also sure that My SD cards %100 works and at is genuine , even i tested it wit H2testw v1.4 and there is no data lost my friend
