I installed a 1TB segate in my XP computer to install W7 on when it gets to me Monday. XP is on a 500 gig hard drive. Partioned the seagate and there is some space at the beggining of it that wont partition, just a few gigs. Is that OK? Also, with W7 on its own drive could you take that drive out and install it in a new computer and have everything work. Thanks for your help.
