Ok, im doing an economy build and salvaged a 80G WD IED, but it has a bunch of personal info on it that i dont want. I would like to use it as the boot drive for the new machine. How do i go about erasing the disk clean and installing a fresh copy of XP on it? Can i slave it on to another system and delete all files? Will booting from OS CD give me an option to reformat? How long will that take?
