Installing fresh copy of OS, can I ERASER entire HD prior?


New Member
I was wondering if there is any way to "shread" the entire hard drive prior to reinstalling windows XP? In other words, I'll end up having to format the hard drive anyway when I reinstall windows XP. What I wanted to do was "Eraser" the entire hard drive so that I know nothing is left behind. Please advise on how I would go about doing this.

I've backed up what I need. All that's left is to wipe clean the hard drive and then reload XP on it. Thank you in advance.
