slave it to another system and do a low level format... OR LOOK UP LOW LEVEL FORMAT / WIPE DISK AND DO IT OFF A BOOTABLE CD.

CCleaner has a drive wipe utility included. It has several preset wipe levels. DOD is 3 pass while the NSA specifies 7 passes. I would go with the 3 pass option since even that will take forever. If it's good enough for the Department Of Defense it should be good enough for what you need it for.

anort3 is right on - you're probably looking at 10 to 12 hours maybe longer. A full wipe writes all zeroes to the drive - takes forever.

Did you select the whole drive or did you leave it at the default? I think by default it only does free space. You have to select entire drive.
