Well my sister receieved a 80GB western digital hard drive to go along with her 40gb maxtor hard drive...she's having some trouble installing it, and to tell you the truth i've built computers, but i've never put more than 2 hard drives in a computer before! So i don't know what needs to be done, so if anyone could give me a step by step process of how it happens, that would be very much appreciated, thank you!
