When you really, really need to destroy data
Researchers at the Georgia Tech Research Institute have developed a machine that destroys a hard disk in a just few seconds. GuardDog uses a 125 pound magnet which scrubs magnetic media of all data. That includes hard drives, video and audio tapes, and USB thumb drives. The large machine is being built with national defense in mind, but could be used by civilian companies as well. Researcher Michael Knotts says there are times when the military and intelligence agencies need to quickly and completely destroy sensitive data.
