I have the same problems few weeks back,ending with 'Dead ext hard drive'. Good thing is hard drive still under warranty,sent back to manufaturer, they are sending me another one, but i lost all data.If you still can open hard drive ,recomend to back up all important data. If  wararrant expired, try to reformat hard drive(you'll lost all data),i had saved a fews hard drive by doing so. Good luck!
