The one i've used for many years is Ontrack's Data Eraser. That's assuming
the application is still going. A lot of Ontrack software has been tacken
over by techno trend. It comes on a floppy disk and you simply insert the
floppy into your floppy drive and reboot. It uses caldera dos to boot with.
You can then select whether you want to simply erase a partition or a
complete drive. You also have the option of controlling how many times the
drive is overewritten. For a complete drive you can also print out a
certificate to say it has been security wiped. Be aware, thought, that if
you have a large drive it can take many hours, if not days, to wipe the
drive.
