If you dont have such a tool or dont wont to use one, you can use dd on Linux 
(Use Knoppix if you don't have it installed)

dd if=/dev/urandom of=/dev/sda bs=1M count=1024

Change /dev/sda with your drive and the count parameter to match your disk 
size. Repeat the procedure two or three times and it's the same as you used 
an overwriting tool.

I've heard it works to drill a hole and put battery acid into the hard disk. 
It destroys the surface, so it isn't readable any more.
