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.
