I recently bought a new Seagate 200gig hd and since I needed to format my current one, I decided to copy over the stuff from my old hd onto the new hd. After formatting the old one and reinstalling windows, everything works fine. However, when I connect the power to the new hd, the system hangs and doesn't do anything. I just see a blank screen as soon as i start up the computer. Anyone have any ideas why this is happening?
