The reality is that it's massive overkill. A dozen years ago, seven passes
would guarantee cleanliness. These days, the way the data's stored on
modern drives, I've seen people argue that one was sufficient, and surely
two would be.
But it's no big deal. I usually do four at a time, shove them into an old,
decommissioned server that I saved for the purpose, and leave dban in the
DVD drive, fire it up, choose that, and the drives, and walk away. The
next day, the following Monday, who cares? I'm mostly using them for
servers that we're about to surplus.
