have you tried removing and putting into a computer to see if you can access it?
if that doesnt work then somehow it got corrupted or it went bad.

Yup the computer doesn't recognize anything at all. I put it into a camera and it says need to be formatted so I do so and it just stays on a screen saying Formatting. IDK whats going on with the stupid thing. Sent HTC a email and maybe they might send me one or something. Who knows it's a shot.

Sounds like its dead. I would just pick up a new one. You can get a 16gb class 6+ for under $30 online.

I love HTC so much! Sent an email out last night, got one back today and they are going to send a new one. Just have to send old one back. Hopefully they wont see my custom roms on there lol. Any ways HTC saves the day once again and I get a good ol 8gb card back.

i would still buy another. there 8GB is straight up Class 2. Barely writes over 2MB/sec. You can buy a class 6 8GB card for less than $15.00 on Newegg shipped.

Hey OP did you lose all your data?? Hopefully night. I think i might just copy my sd to my external tonight just as a backup that you said this...
Thanks...

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...

[Q] SDCARD died on me last night help recovering data?

Hey everyone, I really need your help.
my 16GB microsd died last night, here's what happened:
I had gotten google music beta on wednesday, last night i was showing it to a friend, then clicked home. I have Watchdog installed, which told me music was taking up a lot of CPU, so i went in and killed it. instantly, android notified me that the sdcard had been ejected. then it popped up and told me that a blank card had been inserted. I was confused at first, but didn't do anything with the card, I took it out, reseated it with the phone off, started backup, same issue. I put the card into a card reader on my win7 pc, no luck, the card really is dead. It shows up with a drive letter, but notifies me that the card needs to be formatted.
Does anyone have experience recovering data from flash drives? I always backup my roms to the card, and apps using titanium, but I never ever thought of backing up the entire contents of the sdcard elsewhere. HELP!?

Use that on windows, it worked when my sd got messed up. This is assuming the files are still on the sd and not gone completely. You could try the repair option in windows if you have Vista/7, not sure about macs or linux.

Thanks but right now windows is telling me that the drive is not accessible. recuva is also saying "the parameter is incorrect". I can't see anything on the card. I think i need some low level scan type stuff, but I have no idea what program goes that deep.

Sorry, don't know of any software like that. You may need to format if you can find no solutions.

I had the same problem a couple of weeks ago, but the last application that I used and caused the card's premature death was some FM radio app.
Since it is not recognized in any device whatsoever, I don't see any software that can help you even attempt to recover, fix or format the card.
But I learned a lesson: I always used to do backups once in a while, but when the card fubared I just learnt the hard way that I wish I had made backups more frequent...

[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...

SD Card Issue in S5

Hello All,
Im Hoping Someone Would Be Able to Help me with an issue....
ive got the samsung galaxy s5 SM-G900I with telstra here in Australia, on the 26th of last month i went to my fathers wedding, i was taking photos on my phone with the camera it spent most of its time on the camera app (once closed itself down prob due to inactivity) anyways after a while it stopped taking pictures.... the capture button on screen was grayed out but i could still see through the camera.... i though ok weird and closed the app down and opened it with the same result... then a popup came up that said "Camera Failed" when i pressed ok the camera app closed.... tried to bring it up again and it was a no go so i decided to reboot my phone..... it shut down properly but never turned back on so i though ok maybe it turned itself off so i tried to turn it back on and got nothing..... i pulled the battery out and put it back in and the phone turned on and the camera was working perfectly fine again so i though oh ok glitch but all good.... anyways i went back to taking and i found that all the pics i had taken that day were gone from the SD card...
it took me a minute to relize that all the photos on my card were gone.... i went to investigate and say that the card wasnt mounted under storage and i though all good again and hit mount and nothing happened.... then i saw a notification saying either an unformatted card or an unsupported file system... i checked in another phone with it and got the same issue and it seemed the card had gone bad, anyway i got home that night and plugged the card into my computer and found that the card was reading up as a raw file system.... so i went stright to data recovery but before the data recovery could finish scanning the card all of a sudden there was my sd card reading up perfect in my laptop... which was weird to me as i havnt seen that happen before, so i backed up everything on my card to my computer and plugged the card back into my phone and it came up with a different error i think it said something about the card maybe being corrupt.... so i put it back into my computer and ran a chkdsk on it and it showed that everything on the card was corrupted..... so i decided to wipe the card and start again and i transfered everything back onto it and everything was working perfectly fine as if nothing had happened...anyway fast foward to monday this week and i went to take some photos and recorded a video on my phone (went stright to the SD card) and i checked it afew hours later because i got busy and i had found that everything i had done that day had corrupted and photos that i had taken about 4 or 5 days ago were also corrupted... images that i had seen to be working fine.... so i backed up my SD card again and though ok im gunna have to buy a new sd card and i redirected the save location for photos back to internal storage.... anyway today my SD card was still in my phone... all of my music is on it still and i was listening to music while i was heading out to the shops.... and i noticed that afew of my songs were playing for a second or 2 then skipping to the next or just pausing and throwing an error about the song being corrupt...
so i put the SD Card into my Samsung Galaxy Tab S and the songs that were "Corrupt" on the SD Card were working fine on the tablet..... so i am wondering.... is it the SD Card or the Phone?
thanks Help would be amazing!

sorry about that.... not the best when it comes to that lol, i just edited it i hope it makes it easier to read

I'm not trying to give you a hard time, but that is still hard to read. If I got the gist of your post, you had a camera failed message and apparently SD card corruption.
There isn't enough information (or maybe it's in the middle of those paragraphs) to tell what happened. Probably just a temporary glitch, but you could have anything from an actual camera failure to a physical SD card defect.
Try clearing your system cache. I wouldn't worry about the failed camera message if it doesn't recur. If it does, search for the camera failed threads, Samsung was providing warranty replacements for some early production camera failures.
If you are searching for photos, see if your phone put them on the internal sdcard (since the external SD wasn't accessible). Otherwise you could consider a data recovery app to see if photos can be recovered from your external SD card.
Is your external SD card bad? We don't have enough information to know yet? Do a search for an app to test the card integrity or you can probably use the fsck command to test the card and correct (if possible) filesystem errors, followed by reformatting and remounting the card. The fact that the card was readable on another device doesn't differentiate between an marginal or unstable card and a sound card. You'll have to test and reformat the card to really tell.

thats ok i know your not trying to give me a hard time on it im sorry that its so dificult to read, ill see if i can try this alittle better
on the 26th of last month i was taking photos for my fathers wedding when the camera stopped working, it wouldnt let me take photos so i closed the camera app and opened it again thats when i got the camera failed message
i tried to reboot my phone but it froze during the reboot and didnt start up again so i pulled the battery out and put it back in, when the phone started up again the camera was working perfectly fine but the SD card was coming up as unreconized file system or unformatted,
i got the SD card to my Laptop and the File System Read up RAW i started data recovery and while it was scanning the card everything started working again and i got all my photos back without the need for using data recovery
put the SD card back into my phone and it read corrupt so i reformatted it and restored everything back into it and the card worked fine,
Fast Foward to Monday This Week and i recorded a 10 minute video at 1GB size and took some photos.... and they corrupted.... no issues with the camera or anything like that.
Today i Was Listening to Music that was stored on my SD Card (64GB Class 10 Transcend) and it skipped a song about 2 seconds into it and another song it tried to play and failed coming up with an error about it being corrupt, ive taken the SD Card out of my phone and put it into my Samsung Galaxy Tab S and the songs that were "Corrupt" worked perfectly fine on my tablet
so im wondering if it could be the SD Card or the Card Reader in the Phone? the System Cache in the phone has been cleared.
Thanks i hope thats helped you able to understand it better and again i am sorry for my poor writeing skills

Thank you for going through that again.
The basic question or mystery that we are trying to solve is why does the external SD card only appear to have problems in your phone and not the tablet? And how can we tell if it is a card issue or something other aspect of your phone?
While it could be some problem with your phone e.g. bent or damaged SD card slot, corrupt driver or other causes.. it would be hard to track down without further hints. i.e. there are so many possible causes that we need to narrow it down.
So it's easier to tackle this by elimination. Lets test the hell out of the card because that is easier to do.. and despite the fact that it appears to work in your tablet, it's still more likely to be a card problem. Why would it only affect your phone and not the tablet if it is a card problem? There are lots of reasons, but just to give one example.. it could be a problem on just one area of the card.. and that happens to be where your phone is preferentially storing files.
If that makes sense so far.. then the plan is to see if we can identify a card defect. So.. grab an app that will check for file system errors (chkdsk, fsck, etc), check partition structure and do extended read /write tests on the card. At a glance perhaps one of these apps: Lewy or Dewy.
Most likely you have some bad clusters which fsck or chkdsk could repair. But it's best to run an extended card test.. that may take a few hours but it's still a lot quicker than trying to search for all the possible causes of phone problems. If your card passes with no issues.. I'd be inclined to back up your phone and then install a brand new, 100% fresh and stock firmware temporarily. That should in one swoop tell you if it is a hardware or software issue. Again, we are looking for expedient ways to narrow down the possible causes.

i will give u a hint ... try to make your topics, in your case, a loooooot less than your post so a lot more people would help you.

But it's best to run an extended card test.. that may take a few hours but it's still a lot quicker than trying to search for all the possible causes of phone problems. If your card passes with no issues.. I'd be inclined to back up your phone and then install a brand new, 100% fresh and stock firmware temporarily. That should in one swoop tell you if it is a hardware or software issue. Again, we are looking for expedient ways to narrow down the possible causes.

Im Sorry it took so long to reply to you, The 2 apps u suggested did not work they wouldnt detect the SD Card, i put it into my laptop and backed up my data and i ran a chkdsk on it and it came back clean said nothing was wrong with it, i have hard disk sentinel installed on my laptop and ive run a surface scan on it that is doing read write read test selection on 2 passes and has been running all day.... the first pass came back clean on it but the second pass has picked up 4 bad blocks near the end of it... its come up "7/08/2014 9:43:09 PM ! Verify error, Sector: 99480300" afew times with different sectors on it, im wondering if the camera issue i experenced could have caused my card to screw up like this? or even the phone not booting back up without taking the battery out first after the camera issue happened? would you consider Transcend a good brand for SD Cards? mine was a Transcend Premium 300X Class 10 Micro SD Card 64GB, im thinking of getting a 64gb Samsung Pro Micro Sd Card now... are those good?

Hey mate! finally i have someone who has the same issue as me! this happened to me last week. i was going through my photos and they looked to be all corrupted. i didnt take much notice as i didnt really need them. i was at the gym and my music was all gone. it was all saved to my samsung 32gb SD card. i got home and there was a message saying SD card is damaged. i lost everything. i did a format and nothing happened. it still said SD card failed.
i went and bought a new Samsung Evo 32gb SD card and it is doing the same thing. i plug it into my laptop it works fine. when i chuck it back into my s5 it says its corrupt. i have no idea whats going on. SD card reader in the phone maybe damaged somehow? i dont i have ever dropped my s5. its driving me mad.

My wife's 64GB card is now doing the same. Formatted and working twice. Images all saved to cloud but a pain waiting for it to happen again.
Ordered a new 64GB card today. Hoping that sorts the issue. If not its return to store time. Happy knox is intact.

my galaxy S5 does not read SD card also..
i think most likely is the software issue.

Just wanted to chime in here. I have a hardware failure with my s5 SD reader, and it was my fault. I had to replace my digitizer, hence putting My Straight talk sim into a temp phone for a fee days.
I cut my sim down to nano size for the temp phone, then stuck the now nano sim back in the s5 after repair, I didn't have a sim converter, and ended up bending pins. Thankfully the sim still works but I toasted my SD slot. Not only will it not read any SD card, it breaks any working one i put in it. I'm a hardware guy, so I'm going to give a go at fixing it, but I'm pretty sure the whole assembly is soldered to the board, no replacing this assembly. At least I don't believe so.
