[Gloucs] Fwd: Recycling pcs

[Matthew Phillips]

I feel I have something to offer to this.

Simply booting up a basic Linux live cd and then issuing the shred
command against the drive will wipe it. (in a forensics environment we
would obviously not mount the drive)

shred -f -v -z /dev/sda.  #this will perform 25 iterations and then
end with zeros, -n 5 to speed things up!

And to check if the drive returns any readable data:

cat /dev/sda | hexdump | strings | less

Have fun!
