Against a serious attempt at data recovery, it is worthless. If you have serious concerns with what data can be recovered from you hard drive, don't bother any approach that depends on the drive itself to overwrite the data. In my opinion there are only 2 ways to destoy the data permanently and dependably in a HDD: complete physical destruction of the disks in the drive or a high strength degaussing field.

Naw, I don't have any significant concerns beyond keeping email addresses away from collectors and sellers. But it sounds like anyone who does should schedule a carribean cruise and take a quiet walk around the rail in the middle of the night. [:/)
