How do I sanitize a hard drive?

Watch out for the "back door draft" -- Maybe with your experience and knowledge you'll just
do IA for the JTF-GNO.

there are a few DOD class apps that will wipe drives with many passes -
a search on google.com should provide links to many.

There's a standard DoD wipe protocol, but the DoD itself may no longer
rely on that for maximum safety; I suspect they'll incinerate instead.

It's theoretically possible to read disk at an analog level and then
deduce what has been overwritten. There are three dimensions to do
this in; linear offset, radial offset, and signal depth. Combining
those may allow a particular session to be "tuned in".

The resources to do this are beyond your average script kiddie, sure,
but if it's national budgets or multi-national resources, then worry.

Nope, I was OC OCONUS for the company. I'm a NA for the Corps now in the
Reserves. (MOS 7529)
