My friend is going to give me and extra hard drive he has (40 Gig, I believe). Currently I have a 30 Gig 7200rpm installed. Is it possible to install this hard drive as an additional drive for storage? I have never installed 2 hard drives on one computer before, so excuse my noobness. Is there any reason I shouldnt install it if I can? Please give me as much advise as possible. thanks.
