I have an external hdd plugged into my AEBS, I see the external hdd in Airport Utility but not in Finder. When I click on my AEBS in Finders left pane, nothing is in the right pane and it says Not Connected at top. I formatted the drive Mac OS Extended (journaled). Im trying to use it with Time Machine. It is not a powered drive, its a 2.5" usb powered drive, is that my problem? Airport Utility sees it, so I figured I would be OK.
