Best program for formatting?

Im selling a few hard drives next week and I was wondering, whats the best program to format them? I mean totally as I understand Windows format leaves a trace or something of the data?

Try a wiping program, I use Dariks Boot and Nuke (it's freeware).
It does American DoD, RMCP and even higher level random seed wiping profiles, like Fast PRNG (Mersenne Twister).
I know there are other progs out there that people will recommend but DBan has sufficed my needs and is very easy to use. I've used it at work on decommissioned machines.

cheers bud, used dban. Took 3 1/2 hours to do 2 80gb drives
