I'm giving my SIL my old laptop. I doubt she'd ever try to bring up my deleted files, but JUST IN CASE, what's the best way to get rid of everything where they are relatively very gone? I know she'd NEVER know how to really get SUPER deleted files, so putting in a new harddrive is overkill. I've never installed an OS, so I'd probably screw it up if I formated the entire drive.
