If the filesystem is NTFS, then it's rather trivial to recover overwritten data, due to the journal. While you're probably safe in assuming that the next user won't bother doing anything like that, the only way to truly, and securely remove the previous data, is to wipe out the filesystem too, which means taking out the OS. On the flip, I've been happy with "Eraser": http://eraser.heidi.ie/ Good luck. -- . O . O . O . . O O . . . O . . . O . O O O . O . O O . . O O O O . O . . O O O O . O O O
