I need to wipe my hard drive of all data. So i found this Darik's Boot and Nuke program.
http://www.dban.org/ and also this other program,
http://www.killdisk.com/. Does anyone know which program would be better? Also, if i wipe my hd of all data, does that make it unusable? Or is it just like having a new hd with nothing on it, but still usuable? Or if you have any program that completely wipes a hd, and still makes it usuable to re-install vista on it, reply it back here, thanks!
