Wipe That Hard Disc Clean

Most of you know by now that simply deleting material will not erase it from your hard disc. Until the space on your hard disc occupied by deleted files is used for some other purpose - or is deliberately erased - the "deleted" files will remain and easily can be recovered. Medical and personal files thus remain at risk for accidental or deliberate recovery and misuse until the physical space they occupied is deliberately overwritten or erased.
