I have had my GS3 for a little over a month, rooted and had no issues, I installed another rom with no issue. Unfortunately when I tried to install a CM10 or AOKP rom, each say my ext sd card is damaged and needs to be formatted. I try to format, but it hangs and then just quits without completing the task.
I have tried formatting to fat32 on my PC, downloaded EaseUS Disk utility to format, but none seem to work. When I restore back into the previous rom, it still says damaged and then I can format and start over only in that non AOSP/AOKP rom.
I boot into recovery when the AOSP/AOKP roms are loaded and it wont even mount or format in recovery either.
Any ideas?

I think I read somewhere that in CM10/AOKP that it won't read/understand exFat very well.
So, formatting to Fat32 is definitely the way to go.
When I used some other programs it would say the same thing... that my card was damaged and had to be fixed.
I had a heck of a time finding a program that would do it for me on my 64gb sdxc SanDisk card!
But I found a free one called GUI Fat 32 Format that actually worked.
Click this link and it will start to download:

It didn't work immediately, for me at first, but after a few tries it actually worked very well.
I think that once you get it into Fat32 all of your problems will go away. Hope so anyway.:cyclops:
Let us know if it works!
This seems to have corrected the issue, finally

I had a similar issue... I flashed an AOSP ROM on my phone n it corrupted my sd card and wouldn't format. before formatting I went back to a touchwiz ROM and it still said it was a bad sd card and needed to format I ended up formatting my card in my phone and lost all my data. I put music on my sd card and removed the sd card from my phone before flashing another AOSP ROM. After I installed another AOSP ROM I re-inserted the sd card and it again said it was bad and needed to be reformatted...
So my question is...How can you use a 64gb sd card on an AOSP ROM...I'm back on touchwiz for now. Sd card works fine.
Does formatting the sd card in your phone format it to exfat and not fat32?

Wait, so you're saying that AOKP/CM10 don't have the necessary drivers to handle exFAT formatted sd cards?
Do you remember where/how you came upon this information? Was this issue particular to 64gb SDXC cards vs smaller SDHC cards or maybe to certain classes of cards?
I find this shocking, but I can't say it isn't unfounded.
I have a 64gb uhs-1 sandisk card coming from newegg in a few days, so I'm obviously concerned.
Any insight you could provide is greatly appreciated!
Hey guys... after doing some fooling around I've found out some (useful) information for people with 64 gb sd cards...
1. When you format an sd card while its inside your phone it will format it to exFat.... which is fine if you plan on only staying on TW ROMs. This format is not compatible with TWRP Recovery and has given me issues (causing me to loose all my data on my card) just by flashing an AOSP ROM
2. If you use the program posted in the second post(thanks iomega311) you can format your sd card to Fat32 and it will now work on TW ROMs, TWRP, and AOSP ROMs.
Hope this helps for anyone with SD Card Questions/issues.
In my opinion... Never program sd cards on phone... Always use a computer. Especially if you want it done right!!!!

CM 10 which all the AOSP roms are based off does not support exFAT since it is a proprietary format and they don't want any legal trouble. The best way to format a 64GB gard is with GUI formatter
What allocation size did you guys use? Just got my 64GB SDXC and need to format it so that I can use it on CM10.

i formatted my 64 gb to exfat and i connected my phone to my pc...it reads the card and everything but i am still limited...it seems that the file size limitation of fat32 is still present..
when i go to properties (when the sd card is in my phone) it says file system: generic hierarchical instead of exfat..is that why?
thanks in advance
For what it's worth, I tossed my card in the phone from SanDisk and it was formatted exFat already. Sounds like you might need another format. I don't know why there have been so many problems with these cards. I've read a lot about people frying them while formatting also.

yeah i noticed it was already exfat..i just formatted it again anyway to be safe..i also read about being messing up their cards while formatting
when you plug your phone in a pc does it still show as exfat?
I formatted my 64gb card to exFat back when I had my S3, and it's worked perfectly. Now I just got the S4 and before I root my phones I run through a quick little checklist to make sure I'm good to go; when I checked, though, my computer, too, reads it as "generic hierarchical". I know I formatter it to exFat - that's the only way I was able to make it work in the first place. It doesn't appear to have any file size limitations, but I'll transfer something massive onto it just to check. Unless someone knows this doesn't matter, I'll back it up, reformat it, then refill it and root. I'm kinda lost as to how the computer won't read it as exFat, though.
Well I have a new version of CWM Mod, and apparently when you format the sd-card, it no longer formats the inner sd card but your external sd card. I was really pissed as I lost all my data I had saved, but it also managed to screw up my sd card. Neither of my computers recognize my SD Card and I have no idea how I can go about restoring it. My phone can detect the sd card but it will say its corrupt randomly. So I'm guessing CWM formatted the card in a really screwed up way. Any suggestions brahs?
I'll even try to mount the sd card on CWM but it wont be able to mount it. It's a shame to waste a 32 gig sd card like this
Have you tried to format through the phone storage? Menu/settings/storage/format

Only gives me the option to mount or unmount the SD card
How old is the SD card? This phone is know for eating up the 32 GB cards. I had one for less than 3 weeks and it did the same. I use trwp but there is a thread about cards and our misfortunes with the 32 GB.

Make sure you card is not in exfat. CWM will not read cards in exfat, I had the same problem. If it is you are going to need to format it to fat 32. Most 32gigs sd cards and higher come in exfat now. You are most likey going to have to do it on the computer also it cant be done from CWM.

Yes but my computer won't even detect the SD Card. It was fine and dandy up until yesterday when I hit format on CWM on the SD Card thinking I was formatting the internal storage (since it's labelled /sdcard) but it formatted the actual SD. Windows won't detect my Micro SD and neither will my Mac. However if I put the SD card into my phone and connect via USB, it shows up.

You pressed format /sdcard, and it formatted your extsd? That's a pretty serious bug, so thanks for the heads up. What version of CWM are you running?
Op. I did the same thing a long time ago. I have gotten into the habbit of removing the sd card when I am formatting with a custom recovery. I also back up the sd to my pc and reformat the sd when changing roms. A bit off topic but I also wipe system before flashing a new rom. So far I have avoided many of the issues mentioned day after day. Maybe I am lucky but my wierd habits have been successful so far.

5.8 something. It's weird because it allows for both internal and external SD use. When you backup the first open is to save to external then its internal. First version of CWM i've ever used with such an option.
For anyone wondering about a solution, I used an android 2.3 device which actually has a format option for the SD card and now my computers recognize it again. Life is good

Ok so. At first I thought it was the 32gb card I bought on ebay so I just returned it and bought another class 10 32gb adata card from another seller. This time I did a surface scan and chkdsk ahead of time to make sure everything checked out before I started using it. So as one partition as fat32, everything works fine, md5's verify successfully for nandroids after backing them up to external sd. Until I go to partition the sd card for fat32, and ext4, ext3, fat32 (tried every format). Tried mini partition, easus and Gparted outside of windows. Minitool shows it as "other" format when I try to partition the second ext4 partition. (which is odd)
After I do that, the fat32 begins to not show files that are copied to it. I noticed this while doing a routine nandroid through recovery, then when checking the cwmr folder on the external 32gb card, the files aren't there. NOW after reformatting and testing again, I'm getting the nandroids to show up, but the md5 verification fails.
I'm not sure on what the issue is. I just want to have a damn ext4 partition for mounts2sd.
Is there *anything* I can do further to verify if the card is in fact faulty aside from a surface scan test? Or is that sufficient?
Could it be my phone's sd card reader?
Could the kernel's "usb fast charge" enabled cause an issue?
I'm on the stock latest tmobile-samsung firmware, rooted.
Using stable kernel:
[KERNEL][3.0.90][Tiberius 4.1.2 T989UVMC6][Hercules]
Just to be sure I understand this correctly you want 2 partitions on an SD card? I would not recommend this personally as SD cards are not really designed for that...
But I could be misunderstanding you...
Sent from my SAMSUNG-SGH-T989 using xda app-developers app
Yeah, so I can have a script for mounts2sd use the ext4 partition to install apps to.
However, I'm looking for the sure fire way to test your SD to see if it's faulty or not. Is a surface scan test enough? Is there more?
I guess it's gotta be the card.. Just thought it was odd that it happened with two brand new 32gb sd cards from separate sellers.
Just put in my 8gb and everything works fine, md5's match and everything...
Oh well, return time!
anyone have issues with their sd card?? i have a sandisk ultra sdxc 64gb micro card. i have to format this thing about every 8 hours! insert the card and the phone will not recognize it. i take it out, format it on the pc, insert the card, format it on the phone and its fine. the next day i go to access the card and its not listed in the file manager or in the recovery. in settings i click mount sd card, phone shows "preparing SD card" then nothing. i have to do the whole format thing over again.
any ideas?? is there a firmware update i need? phone is build # 1.54.401.10
doesn't matter what rom i use, i have tried 3...phone is fairly new.
i have done root, s-off, recovery, SU, busybox, etc. phone works great! other than the sd card issue.
thanks
figured it out

well i figured it out...did some sniffing around online and found a thread in the SGSIII forum. someone had a similar issue. apparently after doing a bit of additional reading, the htc one m8 does NOT like exFat cards. so while it CAN accept 64gb and 128gb cards, it doesn't really work right. to fix this i used easeus partition software, deleted the partition on the sd card, created a FAT32 one for 64gb, yes it will do it, and it works perfectly. hope this helps someone else.
I have problems with mine. I have a 128GB and haven't formatted it, and it works fine.
Thanks

Now I've been through, I think, 5 or 6 different 64 gb cards only to have each one corrupted or simply not work right. I always get to the point where I'm copying my music to the card when after a few hours, BAM, everything is gone. I've tried different ways, different types of cards and different hardware to get these cards to work but nothing I seem to do works.
Does anyone know of a foolproof way of getting a 64gb card to work with a T999?
i have a sandisk 64gb formatted as fat32 and its been working fine for 2 years

Did you have any problems getting a 64gb card working prior to this one, did you do anything special for it to work?
Up until the 64gb card, I would pop in a card, transfer everything form my old card and be on my merry way. this is the first time I ran into any problems.
i did have some issues at first when the card was formatted extfat
Are you using cm or touchwiz? And how is the SD card formatted? I just use mine on exFAT with touchwiz and have had 0 problems with both my S3 and S4
I got my new 64gb card. Formatted it to FAT32 using windows 8. Transferred all my music and stuff over to it using win 8. Double checked to make sure everything was there. Put it in my phone and mounted it using CWM and bam, music only goes up to B. Everything else was gone. WTF?
Why does this keep happening. I've tried all different types of cards (except Sandisk for some reason), tried it on both touchwiz and CM (which I'm using now), different ways of formatting (through phone and through the computer. Used Exfat and Fat32), different ways of transferring the data and something always happens when I put it in the phone. Either it destroys the card or some of the data is missing. At least the card still works.
Have you tried copying it to your card while plugged in? Try only copying small chunks at a time.
If youre currently on cm though it really doesnt surprise me that you might be having problems.
