Put the PCBs in kernel mode and copy the ROM. Simple. No soldering.

I know the motor isn't seized. It's a western digital 800BB drive. I tried a board from a similar drive and the motor works and the drive comes up but all blocks just timeout on the DDI. Upon inspection of the original drive's pcb, I see a chip that connects to the motor contacts which has developed a nice little bubble. I believe this chip is the problem.
Question: has anyone found a way to externally spin up the motor while leaving the original pcb attached to the drives internal head stack? I tried attaching the pins from the good pcb to the drive while bending up the 4 pins on the original pcb. The drive seems like it tried to start, but then decided to stop trying, I suppose because the rest of that pcb is getting no feedback or additional signals from the IDE interface.
Can this be done? I just need the drive to spin up, is there a way apart from desoldering and transplanting that motor controller chip? I'm terrible at doing that. I've never been successful as I always botch the soldering job.
