I just bought my first pack of CD-RW's last night, and I think i've managed to ruin 2 of them already . As a test, I first tried burning random files to one, now it doesn't copy anything at al. Second, I copying a game with nero, then it said something about failure, but I don't remember what it was. How do I delete the files off of CD-RW? That was why i pretty much bought them in the first place.
