Fried SD card

Unplugged my Desire from the charger yesterday to discover the SD card had failed totally. Rebooting failed to recognise it and once the screen switched itself off I couldn't get it back on. With SD card removed the phone seems fine but the card is not recognised in any reader now and can't even be reformatted. Did the card just die (it got very hot) or has anyone else had this experience?

A possible SD card failure not caused by the phone or reader. IVe seen this happen and be reported before with certain brands. You should return the SD for a replacement (assuming you have tried all the normal ways to try and read it)

I had my 32GB class 2 do the same thing, I whipped it out and put it into a USB reader then reformatted. I fully believe that its down to not 'ejecting' the card first before unplugging it since I selected the device (card) to be read as a drive.
Just be careful dude, its a royal pain restoring everything, keep a regular backup of your card if you can spare the GB. its's real time saver.
I was a bit worred too about the heat of the device effecting the micro SD card, but from what I read its still well within the safe requirements of the card even at 40C.
most cards come with 2 years+ warrantly especially Sandisk so check that out if you've well and truely screwed the card up (it happens, sadly.)

Had this same problem yesterday with an 8gb card. Just wont but with the card in the phone. So far it has done it twice in a week , one 4gb , one 8gb, both times while I've been using HTC's music application. Don't know if its just a coincidence or not...
Do you use a task killer? Wondered if I'm shutting something I shouldn't be.
Was it a goldcard?

Thanks for the responses. No task killer active and cannot reformat the card because no reader will recognise it. Guess it has gone to the great card graveyard in the sky

May it rest in peace my friend...I sympathise and am sorry for your loss...
Before purchasing a new one make sure that it's not something with the phone.Can you live a few days with the spare 4GB card that came with the phone?Fill it and use that for a few days and see if something similar happens again.Except for if you've been using that already...

could creating a ext cache partition have anything to do with it ?
i had the same problem but managed to get most my data back first time....stupidly i formatted it and carried on using it. couple of days it died compeltly !
learnt my lesson and make sure i backup every few days- pain yes but it's the same with any data if you don't want to lose it back it up !

...premature death announcement there. After a couple of days rest in a darkened jacket pocket, the card is suddenly visible to my laptop again! Clearly on its last legs as several files corrupted and it refuses to reformat but at least I rescued most of the data.
As usual the only backup you ever need is the one you didn't do!

Try formatting with a digital camera...
I had a similar problem with a corrupt SD card in my old phone. Computer wouldn't read it, but managed to format it using a digital camera after which it worked again (and still is).
Might be worth a try before consigning it to the bin...

[Q] SD card unexpectedly removed

Using the pre-installed stock Samsung Class 2 micro SDHC 8gb
Constantly getting this error from the DHD:
"SD card unexpectedly removed"
Symptoms:
1) Usually happens after installing / removing apps.
2) Tends to re-boot by itself after "hang" after about 10 seconds
Note the following items:
1) USB Debugging = ON
2) SIM card is fully inserted
3) SDHC card is fully inserted
4) Using stock ROM
5) PC Error Checking (bad sector) = No error
6) Have tried to format the SDHC. Result = same error
Any ideas on how to troubleshoot tis ?
Is the pre-installed SDHC card at fault ?
Thanks

Another thing you can try is to check with another card (New or Old)
If it still does it....then there shud be some problem with the card holder unit or something...get it replaced mate

Had the same issue. Think your SD card is broken. Mine was. Couldn't even get it to work on a pc. Tried a new SD card and the problem was gone. Just got out of the Vodafone store. They replaced the SD card under warranty.

I've got EXACTLY the same problem. It's bloody crazy!
I read that the phone may not be able to cope, as it's only a class 2 card - but I don't think that is correct, is it?
I've contacted HTC, and they just told me to take it back to the store and ask them to check it out. I'll probably do that in a week or so.

it just happened to me!! randomly. everything was fine and then suddenly it just failed on me. any clue why?

Bundled Samsung SD cards with the latest OTA update are known to fail, search for more info in other threads here to see if you'd qualify for a warranty replacement.

Been happening to me on the stock Samsung class 2 8gb... anyone encountered any problems changing to a class 4 card?
Sent from my Desire HD using XDA App

when I woke up this morning I couldn't access any of the programs on my sd card (SanDisk 16GB Class 2 SDHC), when I rebooted my desire HD the same thing happened. I tried manually mounting it, rebooting like ten times, inserting, ejecting the card etc, nothing would work.
Can't be the phone just smashed a 16GB card over night :/

YES....!! Gggrrrrr! it just happened to me last night. I rebooted my phone after installing some different Apps throughout the day (as is usual in my Android daily life). then after the phone rebooted about 30-45 seconds later i saw the "SD Card unexpectedly removed", thats strange i thought. Couldn't get past that after about another 4 reboots i removed the SD Card and tried it in a card reader on my PC. similar thing, I could ready the file structure on the WIN PC but then about 30 seconds later the drive disappeared and was no longer available. I then re formatted the card (started the process withing the first 30 seconds) and thought that would fix it. Now neither my WIN PC or Desire can read the card. also tried in Lynx Puppy environment but no go.
I think my 16GB Class 2 card is TOASTED. Was it because it used an Ext4 Partition on the card for the past 7 weeks? I heard some people in the site saying that Ext4 can damage your SD Card...?

Had the same problem - lost all my unbacked-up data. Quite disappointing. Bought a new micro SDHC and hasn't had a problem since.

So it's the SD-Card then?
It's happening to me most of the time and it's really anoying!

Yep time to buy a new one.if your luck and still able to access your old card then get it backed up quick.......before it goes tits up.
Sent with Desire.

Just visited the HTC customer center last week to check on this issue. Seems like its got to do with a bad batch of cards.
They replaced an identical Samsung microsd class 2 8gb card to let me use for a couple of days. Told me that If I was to still encounter the same problem, it could be problems with the card reader chasis, and I'd have to leave the phone with them for a couple of days.
I'm happy to report that I have not had 1 single "SD card removed unexpectedly" since I got the new replacement card.
I highly suggest for people facing the same problem to get their cards replaced by the seller or HTC.

I just have the same problem like yours.
I tried many way and methods, It just can't working fine!!
so I buying another sdhc as sandisk 8G class 4
now I have no problem for two months so far.
I am reasonably to Suspected...
that the problem happends cuz this garbage samsung SDHC!!
Change it now! you'll feel like:[what a wonderful world~]

The "telus" version comes with an 8gig class 4 card but upgraded to a 16gig class 10. No problems either way.
Guess Canada nipped it in the bud

I was going fine with the stock 8Gb card and then I replaced it with a class 10 16Gb card and after about a week it started randomly ejecting. The card worked fine in other devices and can always be read in Windows but I guess it's only time - I have had another card go in the past and it's a real downer.
I'm not convinced it's the card. I've tried uninstalling any suspect apps but it hasn't made much difference.
Formatting the card and replacing all the files kind of works but I have still had one random 'eject' in the last 48hrs since I last formatted.
Actually the problem seems to have started when I re-flashed my current rom - Android_Revolution_HD-4G_4.0_beta4
Wish we could find out what is going on here.

Having the exact sample problem, but with a 16g card that I bought several month ago. I have another 16g card, will swap and see if the problem go.

I had this problem as well
So I formatted the SD Card and had the problem since...
however sometimes, it cant seem to recognise some pictures in the card, so i use SD rescanning app...

Heard someone saying this was caused by an OTA, well I had a warning around 2 days before the SD-Card Un-Mounted saying that the Card was in Read-Me format... anyway 2 days later my SD-Card became un-mounted and then became comepletely useless. I was unable to mount it or anything, going to get my dad to ring up HTC, as we rung my carrier and they said the problem 'had never been reported' which is bull**** as theres enough people here with the problem...

sd card suddenly removed ?

Hi guys, I just encountered this problem twice tonight. First, it said "the card is damaged" or something like that then all my photos disappeared (I managed to recover all of them using a recovery software). I formatted and check the card with command promt in windows. Everything was fixed then I put it back to the phone. After a while playing around with it, it said "sd card suddenly/unexpected removed" and again, photos disappeared. I've had this phone for 4 months and never had this problem before. no idea what was going on. I looked this up and it turns out many people used to have this issue with their S3. My card is 32Gb sandisk class 4. Any ideas? right now it's working fine but Im scared that it might corrupt again.

I'm not sure why you formatted it when you put it into your computer, unless it didn't give you an option but i had the same problem happen to me last week and what fixed my problem was I would have my phone's backcover off while tuning the phone on with the microsd card not inserted and after the phone fully boots up then insert your microSD card and it should fix the problem or it did for me atleast, give it a shot.

My s3 still recognized the card. The card was not dead, only the file were corrupted. I formatted it since I thought that would make it "new" again... I also checked bad sectors with windows. Right now it's working fine, I'm just afraid it might happen again and corrupt my photos.
Is class 4 too slow? I have a class 10 SanDisk 32gb but I figured testing it would be a waste of time since I had 4 straight months without problem with this class 4.

When you first put the SD card into your phone months ago, did you format with the phone or the computer? It's always recommended that you format from the phone, before you use it; because it can cause weird bugs down the line. Also, are you running any customs roms or is this happening on stock?

Well I don't remember if I formatted it. I'm on rooted stock JB. I've had this card for 5 months and it has stayed in my s3 since august. There were a couple of times I took it out without un mounting (I didn't know there was an option to unmount it), but that was like months ago. I've done a little search and actually, this is a pretty common thing.

I had the same problem. It would let me view pictures and play mp3's fine, but when I tried playing a flac or video, I would get the same error. I reformatted with android and haven't had a problem since.

It has worked fine since last night. I just reformatted it again by the phone. Hopefully this won't happen again.

Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the “Media” scanning process and significantly draining the battery.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card (made in Korea), and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:
https://play.google.com/store/apps/details?id=com.sdcardmonitor

I had the same problem with a 32gb SanDisk class 10. Files would corrupt, it would occasionally not mount correctly, and I'd frequently get the SD card is Damaged message.
For me, it seems like it was simply a faulty card, as I have an 8GB and 16GB card that both have worked without issue. I sent the 32gb into SanDisk for warranty replacement.

I had this problem for a while. Try formatting the card to fat32 and see if its fixed.

[Q] Is my SD card slot damaged?

Hello everyone.
I have had this tablet for almost a month and so far, I have loved it. Last week, the micro sd card that I ordered arrived. It's a Toshiba Class 10, 32 Gb. I inserted it, and nothing happened... then I tried again and a message appeared, telling me that the card was being prepared.
After a while, another message told me that the card had been "unexpectedly removed". I tried it on my PC and it worked, but started looking out for a solution and found out a program to format it on these forums. I used it to format the card with FAT and tried again.
This time, the card worked for a couple of hours, then the tablet told me that it had been unexpectedly removed again.
I took it out, used my pc to reformat it, put some files and tried it on an Android based media center. It worked and still works.
So, I went to the store and bought several other cards, and so far, either they work for a couple hours before getting the "unexpectedly removed" error... or they don't work at all.
Here's the list of all the cards I have tried:
SanDisk Class 4, 16Gb
Kingston Class 4, 32Gb

Make sure the cards are inserted properly. It's a real pain to put them in...

I know, the SD Slot is unusually deep and it takes some time to get the card into. However, I have inserted it until it "clicks" into place, but nothing works.

Then take back for warranty repair... It's no good if the sd card keeps stuffing up....

[Q] HTC One M8 SD Card randomly unmounts

My apologies if this has been covered, but I did a search and couldn't find the exact issue. Since the first day I bought the HTC One M8 9-10 months ago, the Micro SD card will randomly unmount itself. The only solution I have is to pop it out and pop it back in, then the phone seems to recognize it. Then 10 minutes later, it might give me an error again and say "SD Card unexpectedly removed."
I called tech support awhile back and they hadn't heard of the issue, only solution they could suggest was to wipe the phone and re-install everything. I'd like to avoid that of course.
Any ideas? Card is a Kensington 16GB.

Is the card old? It look like the days of Your 16Gb SD are over, to be sure first try with different one, then buy new one. Like 128Gb now days seems like proper stuff.

Hi I would check to see if the card is genuine also format the card in the phone. Don't forget to backup data first

Try another card, otherwise the SD tray itself may be broken.
I know on past HTC devices, some folks had trouble with the SIM not making proper contact. A piece of tape (on the non-contact side) helped thicken the SIM to make better contact. Not sure if something like this will help here. Of course be careful, as you don't want loose tape getting jammed up in the slot.
