My Book Essential 2.0 Makes Windows XP Pro Hangs At Boot Up

Forgot to tell you that in Device Manager only the driver for the new WD My Book external drive appears, even after I click on View Hidden Devices.  So, I don’t think the driver is the issue.  But as I see the problem, I can delete the new driver but Windows will still probably hang at reboot because the problem is with the external drive being connected to the computer BEFORE the driver is loaded.
