Hello, today i received my sandisk ultra 64gb microsd for the 2nd time since the first one was faulty. it was working fine and i could store my files on but instead of going to delete them, i just formatted it on the samsung galaxy s3. it then said it was a blank sd card so i used my sandisk microsd/microsdhc adapter and put it into my laptop..
