TechwareLabs has published a video and editorial: Hard Drive Destruction - 4 Guns and a Hard Drive. Here's a clip from the editorial:
TechwareLabs takes aim as resident Firearms Specialist Dan Shannon fires upon several hard drives just for fun and to see how well a hard drive would protect you from several different types of rounds. Call this the ultimate data destruction test as we are pretty sure you won't be getting anything from these hard drives any time soon. Let the hard drive massacre begin!
