I have a Dell 8400 XP Pro. It has a 160 GB. Seagate SATA drive. I bought another Seagate 160 GB drive and a Kingwin External enclosure for the SATA drive. It is connected to one of the SATA connectors on the system board. I have an adapter that plugs into the board and has a connector on the rear of the computer. The cable that came with the enclosure connects the two. I got everythig set up and went to My Computer and turned on the power to the enclosure and expected to see the drive indicated on MY Computer, but nothing happened. I plan to bachup my computer to the drive with Ghost 2003. What do I need to do? Please help.
