I accidentally unplugged my external hard drive while copying a movie file
Now when I plug the device in, it clicks as if the comp recognizes it, but it does not show under My Computer.
Under System -> Hardware -> Device Manager -> USB Controllers it shows "USB Mass Storage Device" it indicates the device working properly, with location as "Location 0 (External )"

What can I do to revive my drive???

Try uninstalling it by going to Device Manager and Uninstalling it and Re-install it.
