SD card unreadable

The data from my SD card became partly unreadable, some prgms could not be started and when looking at the root folder of my card I found some items named like ç!é”è((é§éç. Putting the card out and back in didn’t help, only a soft reset did the job. All data was still intact. This thing happened twice untill now. I use a Sandisk 1GB card.
Has anyone had this problem before? I remember reading about the same problem on a forum but couldn't find the posting.

I also experienced the same problem
I had this problem before. When I pulled my Sandisk 1 GB Micro SD and pushed it back in, the System did not recognize my Memory Card. I did it several times and suddenly it came back again.
The trick I used was pushing the Memory upward (against the back of the phone) until the memory was not completely inserted. Roughly about 1/10 of the memory sticks out of the memory slot
I believe this is a major hardware problem with the Memory Slot.

I have had this problem with my 2GB miniSD on my MDA Compact- the first time i had no choice but to re-format the card and start over but second time, re-inserting the card solved the problem.
May be something to do with the card not getting proper contact.

It doesn't work at all anymore!
I've had the same problem with my 1gb SD card since I bought it 2 years ago. It's crap, because copying a movie for instance through the phone (MDA compact) takes forever.
Now I reformatted it, and copied some stuff to it through my card reader. But after putting it back into my phone, the card now is not even seen at all by my phone, and putting it back in my PC doesn't work either... now it's not recognised anywhere anymore...
Anyone, now how to get this fixed?!
Thx!

Try using this utility (or similar) to format your card from a card reader:
http://www.sdcard.org/Downloads.aspx I've used it many times on various cards and seems to do the trick.

Hmmm, thx for hint, but that didn't work either. Since the drive isn't recognised, so does this tool... weird enough the adminstrative tools in windows (drive managament) does see a 1gb drive, but assigning a new drive letter causes an error.... damn... looks like I'll be buying a new SD card.
Does anyone know which brands/types (I now have a 1gb Kinston) have less problems with this, so I can copy files to and from my card though my card reader instead of my phone, without srewing my card up?
Edit: Ha! I formatted my SD card with my digital camera! Leaving just the problem of not being able to copy files to my card through my cardreader...

HD2 destroyed my SD card?

Hello.
After trying the android booting, for 5-6'th time (all working), now the phone can't see the SD card. I thought it was only on the phone, but when i insert the card, in adapter and connect to pc, then NOTHING happens. Like if the card wasn't there.. Hmm, any clue? Usually I just formatted. But now, I can't format a SD card which "isn't there."
Please.

any one??? :S

Sounds like your sd card maybe corrupt, they can die for no apparent reason, its happen to me twice in about 4yrs, tho i always buy from CEX they offer a 1yr warranty & just replace it if its within that time.
There's been a few threads about this;

What is the brand of the memory card?

hey dude,i got the same problem as yours few days ago..cant do much abt it,i just buy a new one..some says the htc that makes the sd card problem

Hi,
My 8 GB sd card lags when i`m scrolling in the file manager.
In addition, the sd card drains the HD2 battery. I loose 35% in 6 hours in flight mode, but only 4% when not in flight mode without the sd card... ( this also yields for the original sandisk 2 GB sd card that was supplied with the phone).
Anyone experienced the same issue?
Is this hardware or software related, and can i fix this myself?

Error check your microSD card using your computer then switch your phone off, put the card back in it and switch your phone back on. The phone will need to index your music/video files etc so go to the relevant tabs and let it do its stuff. See how that helps.

i got a new HD2 and it came with a MicroSD card. I put a couple of cooked ROMs on it and everything was fine for about a week and then the card jsut stopped working. I didnot use it on any other phone or on my PC and it just died.
I own an HTC Hero as well and i put the card in it but it wouldnt recognize it. It has never happened to me before. Never has a card died on me.
I think its a problem with the way the HD2 accesses the SDcard. I wouldnt know specifics but this is the first phone that fried my SD card.

Hey guys, I had the same issue. The SD card stopped working and cannot be formatted now via computer.

My experience with Windows Mobile is that the SD/CF driver is the weakest link. The problem seems to be simultaneous accesses drive it bonkers. I've had the disappearing card problem on other PDAs but usually removing it, doing a reboot with it out, and then inserting it after the reboot is complete will fix it. If it doesn't show up immediately DON'T do anything for a while, it could be doing a CHKDSK on the card, and if you mess with it it will screw it up worse.
Once it shows up what I would recommend is hooking up via USB in CF Disk mode (not Activesync) and doing a format on the drive from Windows.
Last night I got a new 32gb Class 4 MicroSD from China (unnamed) and stuck it in, worked fine, so I backed up all my data to my 'puter off the T-Mobile Class 2 16gb and changed to the new 32gb SD. I started the copy and after a while went to bed.
This morning I got up and it had died during the copy. It was giving me an error on the new MicroSD. It had copied about 75% but was asking to continue or skip. I ended up having to cancel it because it appeared full but it was not. After a reboot I found a ton of FILEXXX.CHK files which indicated it was doing a chkdsk.
Looking at it with SoftWinter.com's Storage Tools the disk was formatted with 512 byte cluster size, way too small for such a large disk, so it was not really out of space just out of cluster nodes. If you have lots of files (I had 10,000) each takes up at least one, even if the file is only 5 bytes. So I reformatted it from the 'puter to 32k cluster size and started the copy over. Seems to be working better now.
Please note that using larger cluster size also will help performance when writing and reading large files as it has to do less directory accesses. Small cluster size is good if you have a lot of small files as it doesn't waste as much space. You lose on average 1/2 the cluster size for each file, as the last node is almost never full.

Hey
i hope for your sake im wrong, but as far as ive been able to find out in my own searching, only san disk has released a 32gb micro sd & its only class 2.
there has been a lot of talk of fake 32gb micro sd's from china, most are actually 4gb re-programed to read as 32gb on your phone or pc, but when you start to fill them with files more than their actual capacity they will only overwrite prev' files & become corrupt.
i actually pick up 1 (32gb) last weekend from a local store, tried to copy the contents of my 16gb, 7gb copied then an error occurred, 2nd attempt 9gb copied but files unreadable by phone or pc, fortunately i always buy from this store & they refunded (£50), straight away, still have 2 16gb cards ive had for about 9mnths with no probs.
there is another longer thread over in the Q&A section, you guys may find some useful feed back over there: http://forum.xda-developers.com/showthread.php?t=646731

Well, the one I got says SanDisk and I have done a full format and surface analysis, it checks out, but I am having trouble writing to it. Not sure what is up with it right now. I knew it was a fake but I thought it was a real fake, not a piece of junk. I hope you are wrong.

I´ve got problems too. I have two SanDisk 16 GB microSDHC cards and both of them are giving similar problems.
I´ve got my HD2 a few days ago and initially I used my old 16 GB card I bought with the X1 (then used with my TP2 and latest the HD2). Everything was working fine initially but then the problems arose. Now I have those problems:
1. Audio Manager has problems reading my music library. iPlay can read it though. Windows Media Player takes a long time building my music library but manages to do that eventually.
2. HTC Album can read my albums sometimes - sometimes not.
3. Resco Photo Manager can read the albums but sometimes it takes a long time to do it.
4. The computer can access the card without any problems after formatting and it seems not to be any problems reading or writing files to it. Installations of cabs stored on the memory card works.
5. Total Commander can access the card without any problems but takes slightly longer time than before to show all folders.
6. Running chkdsk in Windows gives the result of a perfectly working card.
7. The phone is draining battery in an abnormal way with the card inserted.
8. Flashing ROMs from the card worked initially but not any longer. Now it shows the threecolor bootloader screen instead.
The interesting thing is the fact both of my 16 GB cards has the exactly the same symptoms. I will try them in my X1, TP2 and Vivaz later to check out their behaviour.
When I inserts my old 8 GB card (everything made by SanDisk) everything works without any problems. Flashing ROMs work normally etc.
I´m running the Omega XT 3.0 and are using HardSPL3. The 16 GB card has worked perfectly initially with this ROM and HSPL so I don´t think they are related.
The whole thing seems to indicate some kind of "incompatibility" between the phone and the 16 GB cards. It´s like it is unable to handle that size of card correctly. It seems like it "trashes" the file system. My older 16 GB card started to behave badly which caused me to buy a replacement and now that replacement has the exactly the same behaviour.
My 8 GB card is an "ultra" SanDisk card. The troublesome cards are Class 2 cards. I began to have the impression the problem is some kind of issue with Class 2 - because the cards itself seems to be working after formatting.
I have formatted them with either Panasonic SDFormatter and the Format SD application on the phone. Both options gives the same result.

Help on Transfering pics to mircoSD

Alright so Ive been running NAND on my HD2 for 7 months with no issues,
one day the sandisk 16gig microSD failed on me, it wouldnt read,
I contact sandisk and they couldnt offer me a recovering but they did send me to another company,
anything more than 8gig is $175 which is stupid,
I decide to upgrade to a 32gig and I just received it today, my issue is Ive transfer all my music with no issue but the pictures/ camera pics arent showing up.
I formatted the SD card already, anyone know whats going on or what I need to do ?
Thank you

you can do it via computer if you have the detected port or if you don't like me I did it at fed-ex when I had the same problem.

If you have reformated your old SD card then everything is gone from it with no recovering it. I am asumming you formated your new 32G card. As far as your pictures i don't really know what to tell you if they are not showing up on your computer when you have it plugged into your computer with a reader.

ok maybe I should have rephrase it,
the pictures that I transfer from my 4gig sd to my PC is showing,
then from my PC back to my 32gig SD , shows up in my card and in my PC display.
when the 32g goes into the phone, the pictures arent displaying at all.
even on my 4gig card, I have a folder label PICS .
when I try to copy and move the PICS folder into the 32 gig , it is not showing up as soon as its plugged into my phone..
im stump on this one, I havent had the slighest idea what to do now, as Ive search all over the place.
the card is already formatted , a friend said I may need to patitrion the card because its too big ? but I dont see that still helping to display the pictures...
any other ideas guys and gals ?
Thanks

I don't really see partitioning the SD card as something you need to do either as the HD2 is speced as being able to handle a 32G SD card. Besides if you partition the SD card wouldn't that really defeat the purpose of having a 32G card as it would reduce the storage space to whatever you partition it to. Maybe you had a bad format when you formatted it. You could try to format it again, but try to use some different software maybe the formatting tools found here or the Panasonic utility.

wait, lets take a step back. i understand your description of the problem. my question is, when you say you can't see the pictures when you insert the loaded 32gb card in the phone, do you mean the album/gallery application doesn't show them? have you tried seeing if the picture files are there using a file explorer app on the phone (try app called "root explorer")?
if the pictures are appearing in the file explorer but NOT in the album/gallery application, then i suspect it is an issue of the album/gallery application's "cache". these applications typically maintain a cache of thumbnails as well as a background process that periodically monitors changes on your sd card and builds/maintains its cache. try to search for ways to clear the cache to give the background process a clean slate to begin re-indexing your pictures on your new sd card.
let us know if this helps.

acually the gallery , astro viewer, file manager , none of if shows up the pictures,
before I could swap my 4 gig or 16 gig with no issues, I would transfer pics from my PC straight to the phone and use those images or jpgs for either caller IDs or just to have them on my phone.
now, nothing is showing up which is werid , Never had an issue until I swap out this 32gig card, Could it be not formatted right ?
I will check into the cache, not sure how to go about this but I will mess with the phone now

well tried the cache thing , didnt help...
I have no idea whats going on , not sure why it wont read any of the pics in the 32gig card,
but when I plug back my 4gig , all my pics show up.
you guys think this has to do with the way its format ?
I formatted the card thru my computer , not thru the phone, I dont see any options to format it on my phone.
Cyanmods NAND 2.3.2
not sure if that helps

are you hot-swapping your cards?
Reboot the phone with the 32gb card inside and see if the phone picks them up then.
Iyts a known issue with Android when cards are mounted for USB mass storage on the |PC that cards sometimes dont pick up the new files.

I never did try that , thanks man !!

nopes that didnt help at all...

Lost my SD card games.

My phone came with 8gb card in it. I purchased a few games and downloaded a bunch of free ones. I still have 4gb of space yet I can't download anything because the memory is full. I can't move anything else to the sd card because it's all grayed out. I have moved all the apps that would let me.
So I pulled the sd card out and none of my apps have icons anymore. I put the card back in and they didn't come back. Will I have to buy those games again? How do I get more games if the phone says no memory even though there is 4gb of space. The SD says un-mounted in the setting but when I click mount it says SD blank in the top left. When I look at the apps in the apps settings it shows things like Com.andoop.jailbreak and lest my uninstall but not install. They have little black icons instead of the game icons and it has a picture of the micro SD card on the icon.
I wanted to buy a bigger card but this is a nightmare.
Any help would be appreciated.

ye this sometimes happen with apps to sd
usually with the games there is a folder named downloads on the sd card the game apks should be in there, you should be able to reinstall em and it will pick up the old data files on the sd card
note that the sd card wont mount untill you put the case back on the fone as the case has a notch that presses a button to tell the fone that it can be remounted

Thanks
I have the case on but it is still saying blank.
I'll back everything up when I get home and format the card from the phone.

ok what make sd card is it?
do not buy a cheap micro sd card off ebay called memorette
i have had to of the fake cards of 2 different supliers
supposed to be 32gb class 10
turned out to be class 5 4gb
they show 32gb when inserted but if you try and put more than 4gb on it looks like it has transfered but when u mount card back to fone it all but vanished
have u tried putting card into pc/laptop with a usb adaptor?
if you do format the card copy the gameloft folder and the download folder to your pc/laptop first, saves you having to redownload

Thanks
it is the card that came with the phone. Upon closer inspection I seen a break in the SD Card. I will retun it to Rogers tomorrow. I'm going to go buy a new card. A 16 or 32 GB card.

If you an avid gamer I suggest you plump for a 32gb class 10
I've got 8gb of music 12gb of roms
3gb of game loft games
Plus 2gb of play station pocket games
N apps videos n pictures
It all adds up
Why buy a small card n upgrade later might as will do it now saves all the messing about imo
Sent from my R800i using XDA Premium App

lol reboot one or twice you should see everything coming back ...
The SD is not formated it's just that you removed it so android did a cleanup in the interface...
Reboot until you see everything back
and you can't check the content of your SD card or play your games when you are in mass storage mode... (the sd is being used by the computer)

It turned out that my SD card was broken. Of course my wireless provider would not replace it even though they installed it before I bought the phone.
I picked up a 16GB because that is all I could find. 32GB were expensive so I’m not sure I would have bought one if I had found one. You can close this topic you want.
Thanks

[Q] 32 gig card trouble

I have recently purchased a 32gb micro sd card. When I go to put new music on it, it shows from the pc side that it is loading on the external drive(g2 phone) and form the phone it says that it is on there. However when I disconnect the phone only the last album that I put on there stays and the music player will state that "this type of file cannot be played". I have formatted the card through the computer and to no avail, it acts the same.. I did format it on the Android and it worked, temporarily and could load music from my computer for a few days, then it stopped. I am clueless as to what is going on with it. p.s. I tried placing it in a card reader and it did the same, but i did not format it first that time. I seem to think the android is placing a bad file on it causing all these issues. (again I say this because when I format it through the phone it will work temorarilly) any help would be great, I really want toload my phone with music.

Put the same file on a known good SD card. If it stays, it's a bad card. Most of the time the company the card came from will replace it for free (like Wintec did with a bad card that couldn't handle an EXT4 partition).

It is not just one file, it can be multiple files, like I stated in the other thread (I apologize to do two on here, but I rarely have to ask for help, I am usually able to figure the problem out, but this one has got me) I have checked the card with h2test and it states that it does have 32 gigs on it but that the card is corrupt, I have formatted the quick way with sd formatter. What puzzles me is that at one time I was able to load more on it and now I cannot. I feel that there is a fix, I am just not finding it yet.(okay im testing while updating, if i uplug and replug the phone and place music on it, it will only keep the last folder, for instance i put nirvana nevermind on it, it will keep it, i then put a folder with two albums on it, say radiohead the bends and kid a, it will replace the last one , I am certain that space is not the issue, due to having placed less files on it the first time I restored the card agai)

Did you buy this card from ebay? A lot of counterfeit card on there. Cards that say they are 32gb but will only hold a quarter of that.

Try writing zeros with dd to the card... but be careful, dd will destroy anything you point it at, without hesitation. This is a typical dd command:
$dd if=/dev/zero bs=1M count=32000 of=/dev/somepartition

Where did you buy it? Like others have mentioned, it sounds like a counterfeit or broken card.

what is dd, and how can i tell if it is fake, every program ive used to check it goes through 29gigs of partition

DD is found in the terminal emulator on linux/unix systems. Be carefull, you can destroy everythign on a partition with it.
Also, you'll have to reformat afterwards ... the sdcard

Lots of the counterfeits are tampered with to report the "alleged" GB capacity. Its not until you try to transfer the files, that you run into problems and realize you were taken.
Again, where did you buy the card???

I apologize for not having answered your question, I bought it on eBay, I have been given a refund though. Where should I look for one at instead?

I got mine on amazon for like 55 bucks a few weeks ago been working great. It was a class 4 adata with a little blue usb card reader.

okay i bought a sandisk from a trusted store and again same thing, i am lost

What trusted store?

newegg class 4

Yup, that's about the must trusted store there is!
Any luck with lower capacity cards working? I'd say maybe its just a defective card. But its weird to have a string of bad luck like this. Is it possible the SD card tray on your phone is damaged?

Do you have an after market battery? Just curious...
