A DOD level wipe is 3-7 (Depends of classification) random-write passes on the hard drive. I have seen older servers take 2-3 days. As long as he ran them over a degausser (takes 30 Seconds) his disposal method is approved. (BTW I am a DOD contractor and just had to dispose of 652 hard drives from old systems, the degausser was a god-send)
