64GB SD card errors.
Ok, 1st, I wanna say thanks for posting this info... I was completely lost as to why my SGS3 wouldn't recognize my new SanDisk Ultra 64GB SD card. Now, I have a massive problem. I formatted it to fat32, I loaded about 26GB worth of music, movies, pics, nandroid back ups and a few other things that were on my 16GB Samsung SD card. As soon as I installed it, my phone completely bogged down. It literally took me 4 minutes to type a text message b/c it was so slow. I pulled the 64GB card out, it ran like a top. I put the card back in, it gives me the error message saying it is damaged and needs to be formatted. I pull the card out again, re-insert it, it mounts fine, but it is slow as hell again. Any ideas as to what the problem may be? BTW, I'm running AOKP on my phone. My buddy is running the same build, same SD card, no problems at all. Thanks!

crazy.. same here, But im using a verizon s3, the new kern that came with the rom update dosent support exfat.. so I decided to format the card to the fat32, placed it in the phone, says card is damaged must format. so here I am still the same issue.

But this is about the best info ive found. that worked for myself.

I have the same class 10 64gb and it worked perfectly. I had to do nothing. I think it depends on rom

I have a class 10 64GB card, i can format it in exfat no problem, just not fat32.

Any ideas?

Yes. This is a problem with the Card Reader you're using. 64GB cards are SDXC. Cards that are sized up to 32GB are generally SDHC Using an SDHC card reader with a 64GB (SDXC) card will show the incorrect 27.4GB capacity.

Look carefully for a card reader that has the SDXC logo and it should recognize it properly.
