I cannot move files to my hard drive, from my hard drive, or in my hard drive without a high probability of my computer freezing. It took me 3 restarts to transfer 20 files to my iPod. It took me another three restarts to move 6 folders from one location on my hard drive to another. I've cleaned up the drive, I've defragged, and I don't know what else I can do to stop this problem. Do you?
