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 recently bought a brand new sandisk 64gb micro sdxc card for use with my e4gt. When I put it into the phone the phone reads it, but will not give me the option to format it. The only option I have is to mount it, but when doing so it just says it is safe to remove which shows that it is not mounting properly. Should I try buying an sd card reader and formatting it on my computer? Or what else could I do to get it to work? Also, it is running stock leaked GA10 rooted.
I have the same micro sd. For it to work on the phone (for me), I formatted it to fat32 and it worked. Most recently I lost my old card on a trip, bought a new one, I formatted it again to fat32, tossed it in the phone but the phone didn't recognize it, but gave me an option to format it which I did. Then it worked. It might have a bit to do with roms too (I was on stock, then moved to a CM rom)
So you formatted in on your computer? If so which sd card reader did you buy? Could you post a link if possible? And thank you.
Just use any sd adapter and use the format32 gui from Ridgecrop. Roms or builds shouldn't matter once it's properly formatted and mounts.
I have the same Sd card. Sniper and Avatar turned me on to that utility.

My exFAT 64 GB SD Card was working fine when I had it on my TW JB based ROM. I switch over to a AOKP ROM (task's), that corrupted my SD Card, I tried formatting but it wouldn't work. I thought it was a ROM based issue, so I went back to a TW JB based ROM once more...
Now it formatted this time, but the card keeps unmounting itself immediately after I attempt to mount it, telling me that "it's safe to remove" - yet the card seems to be recognized (that's what I think) - anyone else know of a work around for this bizarre problem?
I successfully installed the TNKernel and the Terok Nor ROM on my rooted GT-N5110, but my 64GB MicroSD card was not recognized even when I reformatted it externally as exFAT. I had to format it as FAT32 to make it work. Is this a known issue with the Terok Nor pair, or might there be something else going on? Thanks. {ProfJonathan}
I had a SanDisk 64gb card that I was using with KitKat that stopped working after upgrading to Lollipop. I thought that maybe that issue was caused by not unmounting the card before the upgrade.
I then purchased a PNY 64gb card from Amazon and the behavior is the same, the OS will not recognize the card so I can't mount it. I do have a 32gb card that works fine. Anyone seeing this problem with their G Pad?
It would help if you told us what ROM you are running.
If it's a 64GB card, it's probably formatted exFAT, and your variant of Android 5.0 probably doesn't recognize that.

You must reformat your card to fat32.

Running stock 5.0, rooted, with Sleek kernel. Prior to the upgrade, was running stock 4.4.2 rooted.
64gb cards, as stated in OP.
Edit: Working after a format to fat32. I hadn't thought that was necessary because I didn't have to do it on KK with the same card.
