Not sure if it is possible, but here's what I have done in the past with dead hard drives. If you don't have an oscilloscope (sounds like maybe not) to find out exactly what is going on, get the model and revision number off of the printed circuit board. Go to your favorite on-line auction and search for the model. Look closely at the pictures and/or send a message to the seller to see if their board matches your circuit board. If so, more than likely you can purchase older drives for 10-20 dollars and when it get to your door, just swap the boards being very careful about the connectors and such. They are very delicate so be slow and patient. If all goes well, you will have a repaired hard drive and then just get a thumb drive and make a quick backup before anything else happens.
