Using Dban

[Bryan O'Neal]

Not a fan of dban for that reason. Nwipe using several passes of the rcmp
method is how I usually wipe a drive. The I format it a few times with
random file systems and a few partitions and finally drop a fresh OS on it
before donating. If recycling I typically do one pass with nwipe and take
the drive apart.
