The board that the USB port broke off provides hardware encryption whether you set a password or not. About the only hope for data retrival is to see if you can find an electronics repair shop that can solder on a new port. If you have lots of money you can try professional data recovery. If was a recent purchase and you want to gamble buy identical drive and try switching the boards. They are not interchangable because WD frequently changes them. People trying this have had very limited sucess.
