Blackberry, so sorry for the top post.... As has been mentioned you want a DoD high level wipe... There are various DoD standards depending on how sensitive the data is on a given drive.
I've always used the Boot and Nuke disk images to wipe both extra hard disks and older computers.
Boot and nuke is a bootable image from either floppy or usb drive and is Linux based. I don't remember exactly but I want to say its Debian based.
In any case, that and many other tools are easily found via google and there are a LOT of them out there...
Just one thing to remember though... A full on wipe can take a day or more to complete depending on what level wipe you use and how big the drive is.
Cheers,
Jeff

Do I do it from the commandline or use gparted? I have a cable for attaching
the drives via usb.
