[Cialug] Wiping server hard drives

[David Champion]

I've not seen what 7.62x39 will do, but .308 does a good job on hard drives.
Pistol rounds like 9mm or .45 don't penetrate them well enough, and you'll
have a lot of ricochet if you hit the solid part of the frame.

If you want to be really efficient, you can do 5 or so at a time with a .50
bmg.
