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.)

So I had rooted my phone no problem, been using it for over 2 months now. Again, no problem what so ever. I've just installed CM7 on my mytouch 4g slide and noticed a lot of bugs that still needed to be worked out. so I wiped my phone clean and restored it to an earlier date. After I did that, my sd card has been giving me an error as stated "SD card blank or unsupported filesystem." I've tried formatting it, other SD cards and nothing works. is there anyone that can help?!
i wouldn't know how that happened to your sdcard, but when you say you tried formatting it, how did you format it? i once got an sdcard from an ebay purchase, and it gave me that very same message and was unusable(and formatting it with the phone wasn't working). i made it usable by formatting it with a program called SDFormatter, which i downloaded free for Windows. took a montrously long time for the format, but once it was done, the sdcard was fine.
that sucks that you seem to have lost all your stuff tho?
Try flashing a different ROM. The CM7 we have is still in alpha. Give Team Douche time to work out the bugs.
the problem doesn't seem to be the SD card. because all the data was still there. I tried using another SD card thinking maybe that was the problem but it gave me the same error.
I've already factory reset my phone and its still showing the same problem
Could be dust in the SD card slot or some other debris. Try a little bit of compressed air..

I installed the SDFormatter program you mentioned and formatted my wife's 16gig card. Prior to the format the card wouldn't mount in either of our phones and very sporadically on the PC. Now the card will mount without a problem and is usable again.
Thanks bud,

awesome, glad it worked for you also
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.

So I've been running a CM10 nightly build version for awhile now. No issues whatsoever. However after making no ROM changes to my phone for several weeks, I wokeup this morning with my phone auto rebooting every time it tried to activate the SD card at first boot.
What I've done so far:
Backed up all my photos from the SD card by booting into recovery
Attempted format the SD and all formattable mounts.
Wiping all caches.
Resetting to factory defaults
Recalling on my backup restore point (failed)
What I'm running into:
The SD Card can not be modified. I've tried running the "Fix permissions" utyx on Clockwork recovery, and it is failing. I can't format it, I can't delete anything from it, and I can't add anything to it. Very unusual. Is this a hardware failure? That's the direction I am currently leaning toward.
Thank you.
Just updating on my progress with diagnosis.
Clarification: Mounting the SD to USB in Recovery 'does' allow files to be pulled off. Deleting files from the mounted drive from within windows makes it appear like the files are deleted. Remounting the SD Card show's the files have returned.
Attempted Troubleshooting: Mounted SD card to PC, and ran formatting from PC side. Format, upon reaching 100% says the format has failed. SD Card becomes unreadable from the PC. Dismounting from USB and navigating to "Install zip" show's as no files. Then performing an SD Formatting from recovery on the phone returns all files as if a format has never been run. I am not attempting to format from PC again.
Very frustrating. Second format completed successfully. unmounting the sd card from pc and remounting show'd a clean sd card. Going to "install from sdcard" show'd a blank file system. Unmounting the SD Card from the phone internally via recovery, and remounting it returns all files back to the sd card.
I almost feel like the "read only" switch has somehow been tagged physically on the card.
Edit: don't want to bump my own thread for this partial update. I've had 0 success. The only thing I can think of trying is loading a different recovery engine (maybe TWRP), however I can recall the exact commands and steps to be able to push something like that.
Short and sweet "I think she's dead Jim", unless someone has some input.
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.
So, about the problem. All was fine untill a few hours ago. My note 10 notified me that my SD card is corrupted. OK, no biggie, lets just take it out and put it back in. Worked before, but not today.
Tried the same SD card in my laptop, worked without any problem. I'm feeling trolled. Next i tried with otg sd card adapter. It says "no supported partition was found".
Next, tried another SD card, still nothing. Tried that one with otg - bam, works. So, it's not card that's bad. Tried another one, was empty so i formatted it on phone. Nope - still corrupted. No matter how many times i formatted it, it's always corrupted.
But it works on laptop. All 3 of them work on laptop. Two of them i can see with otg, the one that was all the time in the phone says no supported partition.
Then i thought, maybe the sd reader in phone broke. Rebooted to recovery and guess what? First SD card that showed corrupted message works just fine in recovery. Now, one reset to factory setting would probably solve the problem but i have tons of apps that i'd need to backup and no space to do it because my sd card ain't showing in OS.
All i wanna know is am i doomed to reseting android or is there any trick i could use to avoid that?
Copy all things on your pc,format the SD Card in the Phone and copy all Things back to SD Card
nope, didn't work. had to reflash OS
