I used to work for DoD and GSA. Guess what, they hire off the street!
If you know Linux, boot a disk that will give you a command line, like a
Knoppix cd or an install disk.
dd if=/dev/zero of=/dev/hda bs=1MWARNING! This will destroy ALL data on the
hard drive, all boot sector info and all data on all partitions. It will not
however render the disk useless, you simply have a clean disk that only
needs to have partitions created and a new boot sector installed, which will
happen when you install any OS including Linux or Windows.Incase of
paranoia, repeat process several times.
