ok, my situation is little different... I have WD 1T it was working just fine until today... there was a rain and leak in my office and the water leak in my desk and went thru my HD. I didnt realize until HD stop working then I saw that the USB (2.0) port that connect to Laptop was fried along with 3.0 USB that was connected to HD. I changed the circuit board and now laptop doesnt recognize my HD anymore. But when I plug in it start spinning but its little sound like (krkkrk... krkrkrk... krkrrrk) for few sec and it goes away but still ot able to open the HD. An idea....
