So I just got a new samsung galaxy s2 just on Dec 29th and I got the micro sd 32g that day. Just yesterday my Sd card went blank so I get a notification. I tried formatting the Sd card but it says "erasing" but never finishes formatting. Do I have a faulty Sd card? Is the only way to get a new one? I know I can't exchange cause I threw out the receipt and its past their 15 days exchange policy. And why did this happen?
