12/30   What's the best way in linux to delete or wipe the Master Boot
        Record of a hard disk.  I want to send it somewhere with nothing
        on it. essentially the way a HDD comes from the factory.
        \_ cat </dev/zero >/dev/hda (or /dev/hdb, or whatever) will wipe
           \_ Is there a Linux equivalent?
           the entire disk, including the MBR.  Be careful.
        \_ run FDISK /MBR
           \_ What happens if i run "lilo -u" and I had no MBR backup?
