do they expect you to turn it in with it running or wiped clean? there are softwares out there that will REALLY erase all data on the drive. look for one of those, i.e. wipe drive. typically when you erase something it still resides on the computer's hard drive until that portion of the disk is overwritten. i have recovered (at the file owners request) data that was deleted from a system using special software for that purpose.

if you have the restore discs you could wipe it and restore it and they would probably not notice.
