One disk is failed. It will not read. I'd have to move the platters to a
working chassis.

Chances are that if I can somehow magically move the platters without
causing massive damage to the data that the logic board (containing sector
reallocation information) for it will also work. There's a darn good
chance the motor or heads are just wonky.
