If it took that hard of fall I would almost bet money that the heads slammed into the platters usually when that happens it knocks off or damages the head beyond recovery. if it's spinning up and it making a continuous Ka click ka click ka click and is not reconised , it's dead. if the data is business related or worth alot to you there are several data recovery companies that can disassemble the drive and recover the data . Expensive though.
Good Luck with it..
