Is the drive recognised if you connect it to another computer?
Connect your external drive normaly.
In the controll pannel, open System and sellect the "Material" tab.
Click the Periferals manager button.
Devlop the disks item. You should see your external drive there. Double-click it.
On the bottom of the general tab, it probably say: "Don't use (disabled)"
Change it to "Use..." and click OK.
