I am not sure if you want to make it appear like there is a clean hard drive or do a 'wipe'
so the NSA can't read it. 'fdisk' (linux) has an option to write a empty partition table to a drive,
thus making it appear empty. 'fdisk /mbr' with a dos boot disk will make a Linux drive appear empty,
writes an empty dos partition table. There is a 'wipe' program in Linux, you tell it how many passes to make,
that clears things up a bit.
