OK, I got 2 Computers I use back and forth. The Files on the computer itself ARE FINE. But when I went to stick copies of a very large folder on the stick , THE ENTIRE STICK OF FILES GOT Coruptted. It happened after copying the stuff thats on my WINDOWS 7 Computer. I do know I waited a long time after it copied to remove the stick. Any advice? I did manage to WRITE the files on DATA DVD Disc. So this way I do got a entire copy somewhere besides my COMPUTER DESKTOP.
