Desire killed my 8gb microsd! Help?

Been using this 8gb microsd for a over 2 months and never had a problem was always flashing different roms until last week while i was running sense 2.04 the card just suddenly stopped working completely!
no phone can read it! tried it on a few nokia phones and my htc magic with no luck!
tried the card reader to see if it needs format but the reader can't read it and the reader does work i tried it with other cards...
Does anyone or have an idea what I can do to get it working again? I just want to get my photos on it even if i somehow have to format i can always use a recovery software to get the files back but it's not getting recognized... probably a hardware issue? anyone with any help would be appreciated !

Had the same problem, managed to copy stuff off onto pc but cannot re-format the card.
It says it is locked.

Not really the same thing... I can't even copy my files because it doesn't get detected at all! and now just tried a different card reader so again it doesn't seem to be the reader that the issue... could it be truly dead?

I've had that happen on my G1.
Grab an Ubuntu live disk, boot from it and then plug in your memory card reader with your microsd. It should read it and then you can copy your files over to your HDD. It shouldnt be too hard. If you have an ext partition it will also read that and you can copy the contents over to your hdd. Then using Gparted, you can repartition your sd card and then copy your stuff back over.

this happened to me about 6 weeks back - Desire and WinXP would not mount the card at all, manged to mount it through ubuntu but only got a couple of files (photos) back off the card. Back to the 4Gb as supplied sd just now

Hmm just tried ubuntu guys and didn't seem to get any luck... any other ideas? thx.

I got same problem with froyo, my card is dead. I tried with all methods but no luck.

Yea i thought i would just post that my desire has also killed my 8gb class 2 memory card, no computer will properly recognize it. Cannot format it or anything.
If i brought a 16gb class 6 do you think the phone will kill that as well, just dont wana waste $80.

When this happened to my 4GB card. I booted the phone into recovery mode. Selected 'MS-USB-Toggle' and the PC then picked it up. Was able to copy photos off the card and reformat it.
Give that a try?
If you still don't come right, I think it is safe to say the card is dead. May have just been a faulty card, rather than the phone killing it. (Don't see how that would even be possible, anyway)

put your micro sd in a sd-card adaptor and format via digital-camera.
camera can format killed cards.

Hmmm, not so sure about that. Normally a dead card is a dead card. End of.
However give it a try - will be surprised if it works.

To add another phone to the list: my old HTC Hero toasted my 16GB SDHC.

Yep when I got my first desire it cooked a 16Gb Sandisk card... worked fine for almost 18 months in my Touch HD... less than a week in the Desire... toast!

Me too.
My Desire seems to have fried my 16Gb Sandisk card, although I'm still trying to work out if it's a genuine card as it looks different to my other sandisk cards but the seller assures me it's real. Lost my holiday photos!!!
Just bought another 16Gb card, will see how that goes.
Going to email HTC and see what they say.

I second that, they do particularly well
You can also try a low level format tool
I have used this one before - oldie but goodie - http://hddguru.com/software/2006.04.12-HDD-Low-Level-Format-Tool/ but there are others

this has hapened to my lexar 16gb card.
Ihave a rooted desire; I went into the recovery menu, formatted the card to fat32 100%.
I then plugged it into my w7pc. did a low level format, dskchk-check and fix bad blocks.
then reformatted to ext: 512 and the rest fat32 in my device, been working ever since.

[Q] SD Card problems

Hey everyone,
I've been looking everywhere to get some help with a problem I have with my 32GB SD card.
I'm using an Xperia Play (R800) rooted, unblocked and bloteware removed. Whenever I try to move files, I use one of 2 methods:
1) moving files by connecting the phone to my PC via USB cable and dragging files
2) unmounting the SD card from the phone and use a card reader to move files
In both cases, no matter how I try or how I move the files, eventually the phone will either freeze / freeze + reset / reset / or everything combined several times. Once the system boots up again, it restarts itself several times while trying to read the memory card.
This is really frustrating because it happens to me for the past 4 months, ever since I bought the phone and tried working on it. No matter what I try to do, I always end up with this problem, which eventually leads my SD card to randomly delete files. This includes music, transferred PSX games and such. It's really bugging me, and I really need some help.
If anyone can help me out, I'd deeply appreciate it.
Thanks a bunch in advance
NOTE:
The card was later formatted to 2 partitions: FAT32 and EXT2. This DID NOT help, so re-partitioning my card won't help. Think of something else.

Repartioning your sdcard over and over can result to data loss. Why did you have 2 partitions? You should only be using FAT32 as your primary partion.

I only did that once, and it doesn't have anything to do with the data loss as this happened before I partitioned the SD card. I have 2 partitions for Link2SD app. And even if I do have FAT32 as my primary partition, it still deletes my files at random...

I have 2 partitions for same reason as you Link2SD! That should not be a problem.
Couple of questions
(1) Is this a new SD card and have you used the card before on other phones (Could be a fault with card try different SD card)
(2)Have you been on the same rom since this problem started (If yes i would try a different rom could be a software problem.)
I would try these options to narrow down what the problem is seems like you have tried all the partition and formatting options already :fingers-crossed:

To answer your questions:
1) This SD card has not been used on other phones since this is my FIRST smartphone (took me a while to move to the next step )
2) I never use roms, only the default stock rom.
I find it hard to believe that the SD card is the problem, but what do you think?

I think only way to know if SD card is to blame is try another one,there are apps on Google Play that can test SD card but I don't know how reliable these are.Also you said you deleted bloatware did you delete something you should not have?It would be good if you could try another card then you would know for sure a smaller SD card just to test?

Well, oddly enough the problem WAS the SD card all along! I've been trying a new SD card for the past week and everything went smoothly.
Funny, but the solution was only to replace my SD card.
With that in mind, I'm changing my question. I guess there have been many posts about it, but I'm going to ask this anyway:
What would be the best SD card for the Xperia Play? The bad one I used recently was a SanDisk 32 GB Micro SD card, and the one I'm using now is a small sized 8 GB.
Can anyone help me out on this one?

The best sdcard for the xperia play is a Sandisk class 4 or 6 sd card. Preferably stick with the class 4.

SD card mount problem please help

I've been searching all over for a couple days now and I can't find any solution only people with similar but not exact same problem I'm having. Out of the blue a couple days ago the fat32 partition on my 32GB class10 patriot SD card unmounted and won't mount at all. However the ext4 partition mounts just fine and continues to work as it always has. I also can't plug the card directly into my PC because the adapter that came with the micro SD card appears to not work. My PC doesn't think there is an SD card in it. I tried it with a known good SD card (the 16GB samsung SD card that came with the phone. Which when inserted into the phone mounts and can be used like expected. No new apps where installed or changes made to my phone or the SD card before it stopped working correctly. The same apps and what not have been in use for as long as I have had the 32GB SD card. In fact the currently in use version of CM10.1 has been is use for the last month with no issue regarding the SD card. When I remove the card a notification shows up telling me to insert an SD card. And when I insert the 32GB card the checking SD card notification shows up an a second or two after the SD card is safe to remove notification shows up as if I had told it to unmount the SD card. If I tap on mount SD card in settings the same thing happens. And it also happens after a reboot. CWM can't mount the SD card either. What can I do to fix it so the fat32 partition is usable again?

Have you tried formatting the SD card in recovery?

As I said I can't mount it with CWM either. The card contains the data for my mSecure passwords as that app was forced to the SD card due to JB changes in android so I can't format it until I can recover the data on it. I need a solution to access the data before I can reformat it assuming that it needs to be reformatted. The SD card was supposed to be this fail safe thing and I didn't need to make backups of it as it was the backup storage stuff. So now I'm all freaking out because I can't access it for all the backed up data on top of the data for one critical app that was forced to reside on it. The good news is that only a few apps data is effected by this the bad news is those apps were all very important. I just don't understand why this has happened. And if using a cloud source such as box will be any more secure and safe than using the SD card in light of this; now I don't trust not losing data in the future on a source that was supposed to not have this sort of thing happen.

Maybe the SD card just went bad. Sorry I couldn't be of more help.

No problem, it's a problem no easily solved, and is a long shot finding anyone who will be able to help. I looked at dozens of sites and forum threads and all sorts of other stuff from goggle searches and couldn't find a solution to get it to mount in either the phone or on my PC to recover the data from it and find out for sure if it is a bad card or not. It might still be under warranty. If it's not I'll be ticked considering how much it cost and how little time I've had it.

Try installing Recuva on your PC, if this program doesn't work for you then you might wanna try another more advanced recovery program like R-studio v6 (Shareware) which is easy to use since it's GUI based.
or testdisk-6.14-WIP (Freeware) which includes testdisk_win.exe for partition recovery and photorec_win.exe for files and media recovery, but it's kinda complicated since it's based on Command Prompt or DOS! so you need to google for a guide for how to use it.

Wow I somehow never got notified of this post seeing as I'm just now noticing a reply from months ago. Yes I still can't mount the SD card. I took it out and returned to the stock one that came with my phone. I still have the card as I need to recover the data from it and if not possible wipe it somehow so that I can warranty exchange it. Please do let me know what your solution is so that I can try it and see if it works.

Refresh my memory on what the problem was. This was a while ago lol.

The SD card won't mount in my samsung epic and my windows PCs. This was a sudden without warning signs and with no apparent cause. One moment it was fine and the next moment poof. I was looking for a solution to gain access to the files on it to recover whatever I can and if possible repair the card so that it works again. Assuming that it's not a failure of the card itself. It is within the warranty and well within the life expectancy of it. So I suspect it is not a failure of the card itself. I have the option of using ubuntu or other USB stick bootable options for tools as needed.

S4 Won't read Sd card

I am stumped! I got a Sandisk 64gb sd card for this. Naturally, it came formatted as exfat. From stock through 3 different CM based ROMs, I can't get this S4 to read the SD card. I even downloaded a partition manager to format it to Fat32. I also wiped it and let the phone format it. Even after that it would read it. I know CM now supports exFat format. I even flashed separately the script from the original thread. In any case my laptop has no problem with the sd card. Any help appreciated.

I have a Patriot 32 gb class 10 that was working fine until s couple of days ago. Then the phone said sd card unexpectedly removed. Pulled battery and card nothing. Did a format still nothing put that card in my Asus transformer tablet. read just fine took the card thatvi had in my tablet without formatting it put it in my s4 and it read it. this is my 4th galaxy device they should have figured this out by now. Any suggestions.

The sudden unmounting and/or sd card not being recognized by the S4 and other devices as mentioned is a known issue that is usually SD card related. Sometimes it's just a matter of reformatting your card to Fat32 if your ROM cannot read exFAT cards.
But if that's not your issue or you already reformatted your card to the appropriate format, the SD card has failed and warranty/replacement is suggested.
Can happen to SanDisk cards in addition to other manufacturers.
You may hear this issue being associated to SanDisk cards if only because they are probably the most counterfeited card out in the market. But the issue can occur to non counterfeit cards also.
To reduce your chances of having theses issues happen, always get your cards from reputable sources, in blister original packaging, etc. And if the price looks too good to be true, it most likely is. Even if you take the above precautions, you can still have issues.
Always back up your data for that 'Just in case moment' in case stuff happens.
Purchasing a card whose Manufacturer and/or Seller has an excellent return/exchange policy is a plus.
Having a spare SD card available can help you troubleshoot what your issue may be regarding a defective card, formatting issue, device issue, etc.

You may want to take a look at this thread, as it may help you out:

I started to reply to you but my laptop crashed. Seems this s4 just doesn't like that 64gb sandisk. I had an 8gb card laying around and that worked like a charm. The sandisk was foramted exfat out of the box. I formated fat32 and didn't work. I wiped it and left it without format. Put in the phone to let it format the card. It did--fat32 and then still wouldn't read it or even mount it.
I sure don't have anything to lose by trying a different program to format that card. It could come in handy even if I don't use it in the phone. A camera comes to mind.
Oh yeah, it was easeUS that I used to format the card in the first place. Try something else.

Hmmm...
There have been issues with the 64gb SanDisk cards being read by the S4 as well as other devices as described in my previous post, the Ultra cards from what I've read (red & grey) I have the save card, class 10, running without issue on my previous S3 and current S4.
You may want to try the format link above.
You can always purchase another 64GB card on Amazon with a Seller with many, excellent reviews, and go from there, and return what you have to return

Right. That's the very card I have. Thanks for the help.

Anytime.
Let me know how it goes

This happen to me but with my galaxy s3...turned out sd card was corrupted. Good news was Patriot replaced it with a new one....

If the SD card didn't work in other devices I would seek to exchange it. There are other things I can use it in. I just ordered a 32 GB G skill on new egg. That should do it. The other thing I tried on this sandisk is partition it to 2 smaller ones less than 30 GB each formatted to fat32. Finally it recognized one of those partitions. When I get the other card I'll swap them.

I had the same problem as you OP. I've also downloaded programs to change the format type and stuff, but nothing worked, but I fixed it in a weird way.
My 64gb card didn't work on my samsung. I used many programs to format the card to get it to work, but nothing. What fixed it was....
I took that card and placed it inside my old smartphone (LG G2X). Once placed inside, a pop-up promoted me saying my card was damaged and it will try to fix it. I've tried this on my samsung and it didn't fix it, but once I tried it on this old smartphone, the card for fixed and started to work on my samsung.
I don't know if this could help you, but that's how I fixed my problem.

I had tried that already when the device initially wouldn't read the sd card. When I partitioned the card in FAT32 then the device picked it up, but only one partition of 29GB.

I don't know what your problem is, then. My 64GB Sandisk card works perfectly in my Galaxy 4.

I don't know what me problem is either. When I have the time I going to return to stock and start over. TWRP won't backup onto the SD card either. Wondering if its behaving this way because I rooted the phone before putting SD card in. Though I have done complete wipe (including internal memory) prior to installing current ROM.

I have a SanDisk 64gb micro SD card in my S4, and had it ever since I got the phone about 1.5 years ago. now I am getting the issues you all are getting. I have NOT updated to a new firmware version. and I just backed up and reformatted the card. Very frustrating when all your apps disappear. come to find out they are all being stored on the SD card witch is now not responding... I will try a differect card. I wish they would just leave the phone a lot and stop doing so many updates.. they update one thing it screws up another. Ever since the first update my "Drive" app don't work, and they have no clue why.. not even Samsung knows...

Odd SD Card Response
I have recently upgraded from a ATT Samsung Express (Tracfone) moving my 32GB SD Card into the brand new Galaxy S4 I Knoxed up right out of the box just as a matter of principle. I saferooted the phone and installed TWRP which for some reason refuses to load after a few succesful tries and a backup of my system and restore thern reload of TWRP. My concern in this question (unless some knight in shining armour can make sense of my TWRP issue) is that I am not able to write to the samsung branded SD card I removed from the old phone. I cannot create a ROM directory on it when the phone is connected to the PC, nor can I copy files to it. I had hoped to preserve the photos on the card and suppose I can break down and buy an adapter so it will connect to my PC but the point is it "should" work,, no? I cannot create a directory when the phone is connected to the PC nor can I in ES file Explorer. I've also tried to create a directory in root witth ES and am getting the same error. I just want to get the silly balloons off m screen and get google play to run. I am succesfully rooted. I've tried to reload TWRP with Odin only to get the small print int he uper right hand of the screen then no further. I am able to restore my backups thank God.
This is making me batty on a three step process. The card is my main concern right now as I can't load the ROM to it once I get TWRP figured out. Thanks in advance for all the great help I always get. The better I get the more I'll contribute....I promise.

I bought a sandisk 128gb microsdxc after double checking that it could handle this amount (It's listed a having a max of 256gb) I tried it on my pc and it was golden until I tried to use it on my phone, it shows up and says it is a 128gb sd and lets me use it as a internal or external memory but that's about it, it can't read or write on it and my pc can't detect it when it is on my phone
I also noticed that it doesn't let me take screenshots without my other 16gb sdcard, it says there's not enough space for it even though I've just used 18gb and clearly have enough space
I'm curious if there's a fix like changing to a custom rom, flashing certain file or something like that
Thank you!
Edit: If I use it as external it lets me write and read but it doesn't work as I want it to, also if it's as external it doesn't let me take screenshots as I stated above

I advise trying other brands than Sandisk, if problems persists. There are some problems when using Sandisk SD Cards like sudden read-only SD card. I've tested other cards (Eaget, G.Skill, Gigastone, Samsung, Transcend) and they were better to me.
Also, SD cards should formatted to FAT32 if using it with this device, as Xiaomi did not implement exFAT support for this device. You can search how to format huge cards to FAT32 on Google.
Also, check if your card is genuine. If your card has huge CE stencil on the back, it is fake. Sandisk shouldn't have that mark; it should have serial number and Made In China/Taiwan on it.

I formatted it to fat32 and still no luck, it works with any device except my xiaomi so that's weird, I checked the back and it's genuine btw, I guess I'll just use it on my camera or as a usb, thank you anyways

Sorry bro but Xiaomi didn't fix it lol. I've had this issue constantly on Pie, but it worked OK in Oreo, maybe you downgrade or try another ROM?

same 4 me

Yeah, I agree. I have 2 MicroSD cards that being destroyed by Xiaomi stock ROM simply by self-ejecting itself numerous times, and also it lagged a lot because it always check for 'corruption' where their firmware causes it.
The simple solution that I took is to get a custom ROM and kernel installed on my device and since then, these MicroSD card problems were gone; hell even better that custom ROM / kernel can handle exFAT than that of Xiaomi AndroidOne.
