My method:

1. Boot from Debian install disk
2. while true; num=$((num + 1)); echo "Random $num"; dd if=/dev/random
of=/dev/hda bs=1024000; echo "Zero $num"; dd if=/dev/zero of=/dev/hda
bs=1024000; done
3. Go to bed

Next morning I can see how many times the disk has been overwritten so
far. I'm not DIO or NSA so I'm not overly paranoid nor a particularly
valuable target. I figure the recovery cost for this disk is bare
minimum several tens of thousands of dollars and more likely at least
six figures. I also assume the disk is unlikely to wind up in the wrong
hands given my low value as a target, so this is good enough for me.

Of course, some people would probably argue that even this much effort
belies my statement above about my level of paranoia.
