Hello. I am helping a teacher out with her thumb drive. She lost all her data that was on it. I thought no problem, i should be able to get most of it off using a program. But osx wont even recognize it, and in windows, it comes up but when i click it in my computer it says "insert disk into drive g". So what else could i do to try and save some of her data? I can't even format it, just so she could save the thumb drive..
