I have a 6 gig hard drive that is in my old computer that I am using now. I am almost done buying parts for my new computer build (its been months saving money.) What I want to do though is use my 6 gig HD so that I can install XP on my new computer and everything since I do not have a copy of it anymore. Would it be better for me to install my new HD into my old computer and copy everything over or just put the old HD into the new build? Thanks for the help.
