My Book Essential 3.0TB prevents Windows 7 from booting

Attn heid4055: I don’t believe that’s his problem. I have the exact same issue with two Mybook 3.0 2TB drives. Extremely frustrating. I know for a fact my Dell xps 17 bios is set to boot internal drives, then DVD, then USB. I see no activity on the drive lights if it was indexing and this happens whether I have a hub or not in use. Blinking cursor and my computer is like it is in molasses. If I just pull the USB cable it boots right up. I can also boot with a USB 2.0 buffalo 1tb drive with no problem. It is just the mybook 3.0 Drives that cause the hang. I’m very frustrated and going to try as a last resort to swap the foxconn cables that came with them.
