Hey Warriors - sorry this is not about making money, except in the sense that I'm selling a laptop and I need to effectively and permanently erase all files, data, etc. as there is a ton of stuff on there that I wouldn't want to fall "into the wrong hands" - it's not dirty stuff, just personal stuff, banking and other financial info, docs with my passwords, social security, etc.
I'm nervous about a reformat not *really* doing the trick...
Help! How do I REALLY make the hard drive as if it's never had data on it?
