SD Card Mounting and dis mounting "SD Card stopped un expectedly" Is there a fix?

[AndroidXTC]

Do I need a new handset? I tried three different SD cards a PNY 32GB class 4 a Generic 32 GB class 10 and a SanDisc 32GB class 2. The class 2 card works fine the other two I get the message all the time. The Kid at Micro Center says he has the Generic one I have in his S3 and has no problems at all with error messages whats up with this? I see a ton of complaints if I do a Googlre search on this issue? Who is at fault? Yes all cards were properly formatted in the phone. Im getting ready to dump this thing.

I went with The Big Kahuna (SanDisk 64GB UHS 1) and haven't had any problems. All 3 of those cards should work with no issues, but - do you have access to any other cards that you can try? Perhaps go to Costco and plunk down $10 on a SanDisk Class 10 card and see what happens - it's cheaper than replacing the phone, particularly since you may get a refurbished unit with someone else's problems.

What format are they in?
Fat32 seems to be the format to go with when it comes to higher capacity cards, which ive always done through a computer.
