A quick format will not erase any files. A full format may or may not. Lots of conflicting statements about this online. The best way is to download a bootable disk wipe program. Google one. Burn it to a CD. Wipe disk.
Format it... this can be done when installing or reinstalling the OS.
Thanks, when i do that it asks for product key, then it says its the wrong key. had someone else erase it a few months ago could he have programmed a new key?
