I have a 40gig now and just ordered a 80gig (8mb buffer). my question is: when I install the 80 gig it will be as my primary hard drive (OS hdd) and Ill keep the 40 gig as a secondary. Will I have to do anything to the 40 gig at all when setting up the 80 gig? I mean that having 2 OS's at one time won't affect it? cause I want to just pull stuff from the 40 gig to the 80 once its installed but there will be 2 OS's (xp) in them. Once I get all my files over to the 80 gig I plan to format the 40 gig. Anyone think I have to adjust anything?
