Just bought an SDHC Class 10 64gb SD card from Ebay.
Popped it in an moved all of my 9gb of Roms, Mods and Music over to it.
After about 20 minutes, it started renaming my files and deleting my music.
Took it out and plugged it to the computer.
Noticed it was stocked exFAT.
Downloaded a program to re-format to FAT32.
Re-formated and works perfectly.
Just one problem.
When I do a full wipe in TWRP and flash a new rom, it doesnt let me touch the files on the SD card after flashing the new rom.
It doesn't let me delete, move, download to it, anything.
In order to use the SD card after a full wipe, I have to pop it back into the computer and format it in "My Computer > Right Click on FAT32 > Format".
Which deletes everything on the card.
Is there any way to fix this, or is this because I had to change it from exFAT to FAT32?
Idk lol.
Works perfectly if I just stay on one rom.

It should've been fine if you fat32 formatted on pc, but also try formatting it on your phone in /settings/storage.

Thanks for the help.
I just full wiped and flashed a new rom.
SD card was fully functional.
Maybe just a 1 time thing?
Idk it works now though lol.

Question to throw out there. I have been running the CleanGB rom/ kernel. Switched to the sleeperROM/ shadow kernel. Both are great.
Here is what is weird. After switching to sleeper (not saying it is the ROMs/ kernels) and running for about 3hours my SD card crashed hard. Completely unreadable. Put it into the pc, formatted it, restored only music and pics and a few settings files. This morning decided to backup system with CWM5 but back up routine says no SD card? Booted the phone up and can read the SD card from with in OS. I am going to back up the SD card again with the pc to be safe.
Anyone heard of the SD card getting corrupted 2 days in a row? Should I format it with the phone or pc? The card is a class 10 16gb that is only 6 months old. Haven't seen this ever with this phone/card combo thru 10+ loads of bml roms or mtd roms. Do these things go bad? Suggestions to debug/troubleshoot what could be corrupting the SD card.

Yes they go bad and I would format in phone for best compatibility. Make sure the slot is clean of debris and dust as well.

Thanks. Formatted with pc. Phone at least recognized it. Then formatted with phone. Reloaded files from pc backup. Booted in CWM5. Enjoying SD card goodness.
Again thanks Kenny. Totally forgot about the format from phone. Will continue to back up daily until it appears stable again. And then back to my weekly backups.

I just flashed to CM10M1 and it now tells me that my SD is damaged. I have tried to format it using the phone but the unmounting seems to be taking really long. I have already tried formatting it on my PC, which works, as well as transferring files over, which also works, but when I put it into my phone i comes up with the same error. It is a SanDisk 64GB Mobile Ultra MicroSDXC Class 10. Any help?

I've heard some people had a problem after flashing CM10 with backups done with ROM manager. They said deleting the backups solved it, which doesn't really make sense if you've already formatted the card on your computer, but maybe it'll lead you in the right direction.

What format are you running? I think it has a problem with exFAT format.
Running exfat, will try reformatting to NTFS and will get back to you

Try FAT32. It worked for me. It does say ready to be removed in your storage settings but you should also be able to see the external SD card. Use Solid Explorer and see if you can see the external SD.
Alright basically it was working fine intill I deleted some stuff on my SD card external. I flash between high on android with SD swapped with external apps 2 SD. It basically doesn't work on any cyan based rom it says SD card not installed. But yea it reads it and the downloaded camera s work my second third month flashing I try to make wise chooses but if anyone has suggestions help me out I tried restores different cm ROMs don't know and it takes panorama

Hm. if im not wrong im pretty sure that His rom converts it to a different format... so put ur sd card stuff in ur internal storage or your computer and then insert your sd card go to settings and storage it should say mount sd card and it should connect to it so the phone can understand it. theres an option to format the sd card i recommend just doing that since your data from ur sd is saved somewhere else and tada! you formated your micro sd card
Yeah I think. That might. Work because I just got a new 32 gig sd card and with that apps tosd hack I formatted it because it is kinda annoying that all that data goes to a fake internal with the nice hack but everything is on card ill just start fresh without format like with the old card thanks it worked fine before I formatted the card on high on androud rom great rom for the moment looking for a good touchwiz rom.

Last night I decided to restore my phone back to the stock ROM. I've completed this process countless times before without ever having this problem. I made my backups via Titanium and TWRP recovery. Since I had a lot of photos saved internally, I wanted to move them to my SD card before going back to the stock ROM since they would have been deleted. I used my file manager and MOVED folders containing the pictures that I wanted to save to my SD card. I think this is where my problem stems from. I probably should have copied the folders instead of just moving them. After the stock ROM loaded up I went through the introduction steps and afterwards I noticed the "Your SD card is safe to remove" notification. I went to settings to try and mount the SD card but the setting app ends up crashing. Thinking I made a mistake while going back to stock, I restored my phone back the ROM I was using my backup only to find out that the problem still persisted. The card can be mounted in windows and in recovery mode. I have no idea how to make my phone mount it normally though.
Since you restored stock and are having problems I would flash stock via Odin without the sdcard in the phone just to be sure.

I just tried that and it still didn't mount. I should probably note that it's my 64GB SD card that cannot be mounted and my 16GB one can.
Fat32?

Well then sounds like an issue might be with the format of the card. Try backing it up to pc then formatting it as a fat file system instead of exfat.

I backed up everything from my SD card to my desktop and reformatted it as exFAT (since that's how I originally formatted it) and now my phone can mount it normally again. Still not sure what made it unrecognizable to my phone, but I'm glad I don't have to purchase a new 64GB SD card now. Thanks for helping guys. Much appreciated.

I still suggest using plain fat since exfat is not supported 100% by all roms/kernels. This could save you from issues later if you change from stock roms to custom roms.

Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.
PS It's a genuine Transcend Premium 300x 64GB bought from MyMemory.

Copy everything off sd card. Convert to fat 32. Copy everything back.

I've not tried a reset yet but it's been as good as gold until about an hour ago when it suddenly started flashing between "preparing SD card" & "SD card unexpectedly removed"

I'll give that a go but why has it been working fine for over a month whilst exFAT if that is now the cause?

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know
I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.
I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..
when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
