Now check the data that you already have ... is it intact and valid ? Most likely you did recover bad data as well.
At this point a professional recovery should still be cheap and accesible. You will not pay a fortune. Seek advice of a professional data recovery firm.
If you don't want to do that i would :
- Replace the PCB by a compatible one with the same firmware or "adapt" a PCB to the drive by writting overlays from donor drive.
- Disable re-location in RAM.
- Image/clone the drive by hardware.
- Extract the data.
If you don't have tools and knowledge you can try to clone your drive with the free hddsuperclone tool but again it would be way safer to replace the PCB first ...
Regards and good luck.

From what I have been able to establish, this has caused the 12V TVS diode (?) to burn out. I have removed the offending part and was able to partially recover some of the data on the drive.

But it will drop again after 3 seconds, or 1 minute, or 10 minutes and then sit there and not spin up for another random amount of time.

@ Spildit, So after reading your post again, I am just curious what you think happened to the drive from the wrong power applied that would cause that, and why you say that the data recovered is likely no good.
Assume that the PCB does have further damage, how can you be sure that the data is 100% intact ?

I agree with @rogfanther -- try to clean up the corrosion at the HDA contacts with a soft white pencil eraser. Don't rub too hard. Also measure the voltage at the TVS diode pad. Is it right on +5V, or is it a little low?
