Friend has a crappy old old computer with a less then a gig hard drive, i found a old one from a friend that is a 10gig.. figured the computer wouldnt like anything bigger then that. so can i plug it into my existing extra IDE cables and copy stuff from my hard drive i have now onto that? is it just plug and play, do i have to setup seperate drive for it or does it do it automaticlly? id really like to just clear the new hard drive and re format it, but i dont have any OS avaiable on disk... could i copy my OS while the computer is on with both hard drives pluged in? does any of this make sense
