Let us securely erase your personal files and pictures for only $49.99. We use the only permanent data deletion software certified by NIAP, used by the Department of Defense and Fortune 500 Companies.

Or if that's not good enough, DBAN which is on the System Rescue CD (sysresccd.org). I suppose the average MS-Windows user is not aware of these money-saving methods. Tom
