Squawk, wise to stop when you did. The drive appears to be found but the system doesn't see a file system. A few thoughts come to mind:
Simple things first - try a different USB cable & use a different USB socket. Try it on another computer.
More complicated things - the enclosure could have a problem or the drive could have a problem. Open the enclosure & make sure the data cable is properly seated. Try the drive again. Try another drive in the enclosure.
If you can, try the drive in another enclosure or plugged directly into a computer.
