Actually, there is a better way to do this that is fully DOD approved.

For the past several years, almost all IDE hard drives have had an
INTERNAL TO THE DRIVE "wipe the entire drive" command. This wipe is
EXTREMELY secure, and isn't done by the computer that the drive is
connected to, but rather by the drive itself (once the command is issued).

A professor (Gordon Hughes) at UCSD (Univ. of Calif. San Diego) has
produced a PC program (command line (DOS), I think) that will do such an
erase on a PC, it's called HDDerase and a web search should find it. There
have been a couple of articles on C|Net or Infoworld about this feature
also. The feature has been around for a surprisingly long time, virtually
all IDE and SATA drives have it, but the PC community is surprisingly
ignorant of it.

[I THINK that HDDerase has an option to issue the command to every drive
in the PC at once]




Thanks Barry. I was able to reference information from the HDDerase page
(it doesn't do SCSI) to another page (and device) that does address all
three (IDE/SATA/SCSI).
