Last night I turned off my phone to put my sim in another phone, but when I turned it back on my sd card had suddenly become heavily corrupted. About 10 folders on the card had completely disappeared (nothing important thankfully), and there were about 50 random gibberish files on the root of the card.
I did a chkdsk using Windows which found loads of errors, but I noticed that some files I created after that were also disappearing (such as an sms backup). I ran chkdsk again - more errors.
I backed up what I could and transferred them to my laptop, then wiped the phone and completely reformatted the card, including repartitioning the fat32 and sd-ext partitions. I'm running a different rom now and everything seems to be fine.
The question is, does a complete format fix the card, or should I expect it to happen again?
It's a Samsung 16GB class 10 card, bought directly from Amazon, so I'm presuming it's not fake.
It'll work fine unless that virus hits again.

My SD card is in one or another way corrupt, I think. The system apps won't read the SD card. It's very strange, because I can browse the whole card on my computer and in ES File Explorer too. The Camera app can store images captured with the device, but not view them ...
I've tried to fix it with flashing ViperS 1.3.5 over my ROM again without wiping to see if there were any corrupted systemfiles, but no. That didn't work. So I mounted the SD card to my PC and backed it up, re-partitionated it and copied the backup back to the SD card. Still, the same problem is there. So I rebooted my phone into Recovery (4ext), tried to fix the permissions from there, and nothing worked. I checked the partition aligment and it showed me that the Fat32 partition was not perfectly aligned. So I deleted all partitions from the SD card using recovery (Fat32 and Ext4) and re-partitionated it from there, both Fat32 and Ext4.
Then, I tested the partition aligment and it showed me that both partitions was perfectly aligned. I rebooted and hoped it should work now, but no.
So this is pretty frustrating. Is the WHOLE SD card corrupt or something? My phone manages to load all my apps from the Ext4 partition, so I don't think that's the problem.
PLEASE!!! HELP!!!!!
The problem seem to have fixed itself ...! It's very strange, because almost every time I'm starting new [Q] Threads, the phone fixes itself... Strange -.- But, can someone tell me what caused the problem if it appears again?

Very strange I'm not sure what the issue was. I know with my SD card it showed corrupt or damaged SD but yet ran perfectly on my card reader.I formatted on my computer but still said damaged card. so I figured I needed to format through recovery yet when I tried to go to recovery it would say SD card needed. So I ended up pulling battery And getting into recovery that way then I was able to format. After I formatted from recovery the card was once more able to be detected and the error message stopped. It is a 64 gig. Maybe somehow your card wasn't formatting correctly. But how it fixed itself is very strange. I know in my case I thought I had a bad or damaged card because it kept saying damaged and was not able to be recognized because it needed to be correctly formatted even though I'd formatted it on the computer before hand. Maybe in your case it was an issue like that? Not sure but glad you got your issue fixed. SD cards can be touchy sometimes. In my case I had to format twice before it was recognised.

Dude, I'm going to get you to post threads about my problems too and see if they miraculously cure!
Maybe you should make a thread about a problem with you bank account because it doesn't have $10,000,000 in it! See if that's suddenly fixed. hahaha
As for the SD Card, did it suddenly work right after a reboot? Anyway I agree with Realsis. You can probably cure this problem for good by formatting the SD card, even if it's working now. Just save the contents to your computer first so you don't lose everything.
I'll try to keep this as succinct as possible.
Galaxy Note 2, Android 4.1.2, Rooted.
Few weeks ago began having trouble with audio play back. Any file longer than 5-10 minutes (audiobooks, podcasts etc) would either not playback at all or would after playing for 5 or 6 minutes begin jumping and skipping and then eventually skip to the next track. If I tried to select a point in the play back the song would skip.
Found that if I downloaded the files directly to the San Disk 64 gb SD card these problems would happen but if I downloaded them directly to the phone's internal storage it was fine. This pointed to me that the problem was with the SD card. Also noticed at this point that if I deleted files on the SD card then unmounted the SD card and remounted the deleted files would re-appear.
I re-formatted the SD card using my phone which didn't solve the problem all of the files were back again. I re-formatted the SD card on my mac to exFAT and plugged it in only to find all of the files present again. I used my Windows partition on my Mac to reformat the drive using Windows and found the same problem yet again.
This lead me to believe that the problem was with my phone. So I reformatted the SD card using my computer, and then did a factory reset of my phone. Low and behold I plug my SD card back into my phone only to find the 32 GB of files on the SD card present again. At this point it really didn't seem to make sense. I had formatted the SD card on my computer, opened it and found it to be empty. I then ejected it and plugged it in to find 32 GB of files on it. All accessible and playable, except for the skipping as mentioned above.
So I tried one last attempt. I unmounted the SD card, and factory reset my phone again. Then plugged the SD card into my computer and using the mac disk utility I reformatted the drive using the 7-pass erase system (which according to the description on my computer is good enough for the department of defense).
After waiting two and half days for the reformatting to be done I plugged my SD card into my factory reset phone and lo and behold the 32 GB of files have returned.
At this point I have accepted that I need a new SD card but this honestly doesn't seem possible anymore. Does anyone have any advice? Or heard of anything happening like this before?
Thanks so much for taking the time to read this huge message everyone, I really appreciate it.
I have a 64gb ultra card that caused my phone to reboot. It wiped itself of all my needed emergency data (nandroids, Rom install files)
The reboots started randomly after not changing anything for weeks. I did my usual nandroid back up using twrp then rebooted the system. On my way to work the phone rebooted 5 times in a row so I tried to wipe cache and Dalvik to fix it... But it didn't help.
I wiped everything and was going to do a fresh install but my memory card was missing my files (folders were there but data is missing in folders
Luckily I had a old install file for acr that I used for emergency. After fresh install it still was rebooting... I removed the memory card and it has been without issues.
Anyone have any advice to why this would happen? Is it just the phone hates exFAT file system? Or do I have a faulty card...
I'm currently formatting (full format not quick format) the card but I learned my lesson to not back up to external storage

Had a similar issue. Only noticed it when I went to flash a new kernel and my phone would boot up fine, then reboot constantly at right about 1 minute and 30 seconds exactly each time. Not sure if it is the SD card failing or what...
That said, i noticed as well that my nandroids that would usually restore fine would now fail. I ended up deleting my back ups since they weren't working, then backing up all other content to my PC. Formatted SD Card in the phone, and everything seems to be fine now. All other files on my SD Card seemed fine, but im backing up from now on to my internal memory.
Had similar recurring issues with a Sandisk 128g card. Had formatted FAT32 as well as exFAT and was finding that I'd do a Nandroid, reboot, then the handset would report that the sdcard was unformatted. I'm still not quite sure that I've got things figured out, but I did a complete reformat (long version, not quick) on my Windows 7 PC and then inserted the card into the M8. Rebooted once and the handset still recognized, so rebooted into recovery and did a Nandroid. The recovery recognized the nandroid, and I rebooted to ROM one more time. Everything was fine.
I do keep a backup of my sdcard contents (have had more than one card go south through the years); restored the backup and reinserted the card and looks okay now.
I can't say whether FAT32 is more stable than exFAT because I've had it happen with both formats on this particular card. If you do have recurring issues with the card after complete reformatting, I would suggest a warranty return. (I did that with an older 64g card recently that failed seriously --- the microcontroller was making the card suddenly get red hot.)
I've had my Idol 3 for a couple of weeks now and I just love it . . . so do my 'green' friends! However . . .
My Idol 3 got a major upgrade today, and now the phone won't permit mounting of the SD card . . . home of many apps!
The option under Settings/Storage is not greyed out, it's just that when I tap 'Mount SD card' nothing happens. I'm also getting a continuous notice, i.e. "SD card safe to remove".
The card was not removed either before or after the upgrade, but since I have had the above problem I have done reboots, restarts and hard reboots, and and have removed and replaced the card a couple of times . . . . I'm at a loss on this one!
Does anyone have any suggestions that will help me get the SD card mounted please?
Many thanks!
Just maybe a very strange coincidence here. I have been using the same 32gb sd card since I bought this phone and never had a single issue with the card or the phone (related to the sd card). This morning I checked to see if there was an update, I did not download or install it (since I'm rooted) but man ever since that moment I have been having f-ed up sd card issues. The same types of problems with it randomly unmounting the card and telling me the card is safe to remove, finding the card unmounted and touching the Mount button does nothing and just now I removed the card and my Chromebook is asking if I want to format it... WTF?
All this makes me wonder if Alcatel secretly installed some updates in the background today even though I did not intend for a system update. Hmmm.
I had similar issues with a sandisk microsd.....with it randomly losing everything on the sd....I switched to a samsung microsd and the issue went away so I think it's just very picky with the cards and you should try different manufacturers...also fat32 seemed more reliable than exfat. Samsung and Adata are two I had good results with outside sandisk which I previously considered the gold standard.
Thanks folks.
At this time I don't think it's an SD card issue unless the update corrupted it.
I mean, it was fine before the upgrade guvnor!

Backup the data to pc...format the card in the phone...copy the data back.
Same happened to me on the first OTA update and on this OTA update. I took my SD card out, put in a computer, copied all my files to a desktop folder, re-formatted the SD card, moved all my files from the desktop back on to the SD card once the format was complete and the phone mounted the card no problem. Total PITA and will consume about an hour and a half of your time to do all this. Not sure why this keeps happening on OTA updates, but next time, if Alcatel releases another OTA update, move all your apps back to the phone and remove your SD card prior to initiating an update. Only think I can think of?
Thanks both. Formatting is apparently the only way to go except that my computer wouldn't read the card via the phone.
Soooooo, I have mounted the micro SD in an adapter, and the card is currently being copied to my computer.
I'll let you know how that goes after I've done the format and copied things back.
Maybe just removing the SD card prior to an upgrade will prevent corruptions, or do you think that the upgrade 'needs' the SD card in place?

As the external sd is considered "optional" there is no reason you can't pull it prior to doing an upgrade to eliminate the chance of it getting corrupted.
If you have TWRP flashed and your situation is like mine was you'd find IT could read the card just fine and adb access while in TWRP copied off the data for me so seems related to the actual rom.
The solution
As some of you may have expected, and suggested, I was able to resolve my issue by . . .
1 Backing up the data on the SD card
2 Formatting the SD card
3 Copying my data back to the SD card
However, the .android_secure folder on the SD card was 'locked' by the phone, so I removed it and using Windows Explorer I copied the contents - all my apps that had been moved to the SD card - manually.
If you go this route yourself, your 'favorites' that you dragged to the home screen will be missing, so you'll have to re-do that process. It only takes a matter of minutes.
I want to thank those of you who responded with suggestions that pushed me all the way to the top of my 'success' mountain. The view is great!
Now if only the upgrade hadn't corrupted my SD card in the first place. Grrrrrr!
However, for those that don't realize it, the Idol 3 is a terrific phone that is soon to increase in popularity and recognition.

You might consider installing syncthing and running it on the pc and phone...it uses p2p technology to sync folders between devices....open source version of bittorrent sync. Glad you are back up and running.
I got a new phone today (ZTE ZMAX Pro) and I took the SD card from my old phone and put it in my new one. I formatted it, unmounted it, and removed it properly. Whenever I try to format it as internal on my new phone, it sticks on 20% and comes up with the following error message: "java.util.concurrent.TimeoutException:Thread Binder_6 gave up waiting for partitionPrivate after 180000ms." I also got another one, the only difference being "Thread Binder_B."
So, I restarted it, and wouldn't you know it - it recognized the card. So, I formatted it for photo swapping or whatever it is, and it worked. I then tried formatting as internal, and it did the same thing I mentioned earlier. So, the card will work as usual after some restarts and removals, but is it pretty much screwed for internal formatting?
The card is a 64 GB SanDisk, and it works just fine on my computer.
EDIT: I just tried with a 16gb card, and it worked fine. I guess the question now is: is the 64 gb card able to be saved?
