[NTLUG:Discuss] Formatting hard drive

A quick Google search came for "clean hard drive dd" came
up with "DiskZapper" -- a freeware utility for wiping hard
drives to binary zero from a boot floppy or CD.  It's described at 
http://www.icewalkers.com/Linux/Software/519960/Diskzapper.html ,
or do a Google search for "diskzapper".

Personally I've often used the dd(1) command to wipe hard drives;
I'll boot with the RH install disks but abort the installation after
a shell prompt is available on an alternate console (Shift+Alt+F3,
I think), then I run a command similar to

   # dd if=/dev/zero of=/dev/hda1

to fill /dev/hda1 with binary zeroes.  One could probably add bs= and
count= options to dd(1) to get it to run a bit quicker.
