First I am running win xp home , I replaced my hard drive 2 mo. ago with a much larger drive. I have made a deal to trade the hard drive to somone for another piece of computer hardware. The old HD still has my OS on it and some other personal info so I would like to know the easiest way to clean off all the old info and deliver a freshly formated HD to the person I am trading with. I only have 2 ide ports on my computer and I have 4 devices already on them . HD ,dvd,cdr/rw,cd rom. Thanks for reading.
