I now have my system set up with 2 hard drives. I bought a 120 gig, but for some reason couldn't configure it as the primary drive, so I have my 40 gig as the primary(c and the 120 as my f: drive. I want to put windows on the 40, and everything else on the 120. My question is if I put windows on the 40 gig, and all programs on the 120 gig, can I do a reformat at a later date on the 40 gig, and then be able to run all my programs, or will they have to be reinstalled as well? If they have to be reinstalled, then I might as well use the 120 gig for just data. Wanna kill these ads? We can help!
