Hey everyone, I just got a new laptop and am giving my old computer to my Dad. I have some things on this hard drive I would rather not let him discover that even I don't know about and might not exist but don't want to take any chances. I need to know how to reformat it (aka delete the entire thing and start from scratch not sure if reformat was the right term). Anywho I know there are some programs that cost money and I was wondering if anyone knew of any that were free or not (willing to pay for it if good). If anyone knows anything please let me know.
