Government organisations, at least in the UK use software like Blancco to wipe disks before they send them off for destruction. It basically just overwrites the disk several times. Probably similar software that Hillary got her cronies to wipe her server with.
Obviously in this case they wouldn't be able to do that, as they need to at least present a working machine, I guess they panicked and just deleted the files and didn't have time to do it properly.
