I am having the same issue. It is with all SD-Cards I try after some time. I have 2 32gb Sandisk class 10 that I tried and a handful of 2 and 4 gb class 4 and class 6 cards. After sometime, 20 minutes to a couple of hours I starting getting the "SD Card unexpectedly removed" Then a quick scanning s Card message. I tried formatting the cards with different computers and even using my Linux machine to see if it would fix it.

Has anyone come up with a solution yet? Should I swap the phone out for another one since I have ruled out the SD-Card as being the problem.

My 14 days hits this weekend and it is easier to get things done at T-Mobile before that time frame expires.

All fat32 for me. Phone is stock, holding out on root for awhile so I can learn why Touchwiz is so hated.

I tried ExFAT, but the phone did not recognize it at all.

I wonder if anyone has had this issue with a Samsung brand card?

I formatted mine to exfat to see what would happen. I checked online and this phone supports exfat natively. I moved my files back on to the card after the format and then tossed it in the phone and it worked. It has been over an hour and still has not removed itself unexpectedly.

Will report back in tomorrow after I give it some time to settle.

It is still removing itself almost everytime the phone goes to sleep. The last time it actually unmounted and tols me it was safe to remove the sd card when I woke the phone up.

What cards are people running? I have 2 I am testing this with:

SanDisk ultra 32GB SD-HC U1 (comparable to class 10), 1 is formatted to exfat and is half filled with mp3's, the other is fat32 and half filed with mp3's.

The mp3's are different on each card, I have a folder of music that I always throw back on the card but thought it might be corrupted so last night I made a new folder and added fresh music to see if that was the issue.

I found the official sd formatter program from the SD Alliance to try. I just formatted 1 of the cards with it and am moving the music back now. It will be a while though. From sd to computer the speeds are 12 to 30 MB/s but from computer to sd it is 2 to 5 MB/s?

Hope to have this figured out by the end of the day.
