This is a cruddy situation. If you can find an identical model, you can try swapping out the PCB boards between the two.
If you can find someone with mucho skill, they might be able to hack some solder job directly to the pins leading from the PCB to the disk housing.

But that's an ugly mess. When I've experience situations like this in the past I've normally had to suck it up and count it as a loss.
There are data recovery companies out there that have the resources to easily recover the data off something like this but they aren't cheap.
