RE: Hard Drive data security

["D. Weiss" <David () cawdgw net>]

The only real way to destroy the data is either to sand the platters off or
melt the whole thing down. Sanding is easier and if you use a nice fine
grade sand paper as the last sanding, you can get the disks engraved for IT
awards and whatnot.

Paul,

Try the non-techie approach....after they verify that your hard drive is
bad...then take a hammer to the disk...pound on it a few dozen times...then
give it to them.

Why do they want your bad hard drive anyway?
