That is a very poor way to wipe a disk. The data will still be recoverable 
with the right hardware/tools. Most of the programs designed to make data 
unrecoverable include several passes where random data is written to the disk. 
IIRC, you need at least six different writes of data to truly make the 
information unrecoverable.
