Hmmmmmm.... strange problem here. I've successfully cloned my old master (40G Maxtor) to my new slave (120G WD). I then removed the old master and made the slave the new master. The 40G Maxtor is now completely removed from the system. Now when I reboot the computer (a 2.8GHz P4), the hd won't boot at first. The computer will only boot if I enter BIOS and then exit by rebooting. The computer will then take about 3 minutes before it will boot successfully into XP Pro. In summary, the computer will not boot the hd from cold start. It fails and asks for a "boot disc to be inserted". Once I enter->exit BIOS it will then boot, but only after 3 minutes. Any help will be appreciated.
