The version of wipedisk I've used in the past was made by John Stanish. Unfortunately it looks like the original distribution website is down. It was a pretty simple program. One would boot to DOS, and then start the shredding with a DOS command, with command line parameters. It was pretty slow for smaller hard drives. I'd hat to imagine wiping/shredding a terabyte drive.
Of course, a good Degausser is effective with wiping the hard drives. But, it is hard on the hard drives (i.e. probably no longer functioning). I think it was generally OK for wiping tapes of all sorts, but I had troubles reformatting some floppy disks after degaussing.
