Refers to a
software utility used to completely wipe-out
hard disk
drives. This type of utility can usually overwrite single files, unused
space on a disk, or a whole disk drive, using a series of
algorithms to make it
highly unlikely that anyone could ever retrieve the original data from the disk.

Deleted Files Completely Erased?" in the "Did
You Know . . . ?" section of Webopedia.
