I use and recommend DBAN myself. It's the only free program out there that will do multiple drives at once. There have been plenty of times I've had 10 - 12 drives wiping simultaneously on my wipe system. I only recommend doing that many drives at once on a system with high BUS bandwidth. Very handy.
If anyone knows of another wiper that will handle multiple drives at the same time I'd like to know about it.
