Then again they could just be perpetuating the paranoia, so that unsuspecting companies will continue to waste big $ on their services. As I noted in an earlier response, I was only told to degauss the media, then write low values over the entirety (protecting crypto data - DD Top Secret classified installation.) After this process was completed the media was disposed by a civilian trash company - landfill material.
Beware of hands in your pockets, especially if you have deep ones. David J.

I also happen to know that several of these "agencies" when doing drive disposal, literally drill holes in their drives then incinerate them. That is after they wipe the drive clean several times. I'd assume that there is a reason for such paranoia, wouldn't you? Or do you think they are just playing it super safe?
