Degauss and Destroy

If you combine the DF-4 with either the LM-4E or the LM-4 using a conveyor belt (sold separately) then you can create a Degauss and Destroy device that will first degauss hard disk drives (to sanitise the information) and then bend, shatter, puncture or crush the hard drive, rendering the media un-bootable and un-repairable. This is useful since the NSA specifications for the erasure of sensitive information on hard disk drives declares:

The hard drive must be sanitized using an NSA/CSS evaluated degausser listed in the NSA/CSS Evaluated Products List-Degausser. It is also highly recommended that the hard disk drive be physically damaged prior to release.
