I can tell you how to do it with a Windows XP CD. Put the CD in your CD player, boot, and, when asked to boot from the CD, do it. After it does its thing, you'll get an option to format your disk. Then, format it. The only problem is that then you'll have it formatted for Windows XP.
So I guess this isn't what you want. Not sure what you have in mind, but to "wipe your disk" you'll need to do it by formatting it. A format relies on the OS for a format.
