Does it spin up? You may need to replace the PCB, but most newer drives require that you swap the firmware chip as well. You will need a good PCB from hte identical model drive. Move the firmware chip fromt he pld PCB to the ne one and re-attach it to the drive. This is going to require some soldering skill to attempt, but if the drive still spins its most likely the PCB and can POTENTIALLY with great care, be recovered.
