What would be stored in the controller board?  Geometry & heads & 
platters, so if there was a variant of the drive that didn't have the 
chip fault these should be the same.  The other thing would be the list 
of bad blocks that have been remapped around, which is more of a 
problem.  Even if you don't write to the drive, you would not be 
guaranteed that you were reading the right physical sector for the 
logical sector requested.  I don't know what percentage of the blocks 
would be remapped.

My take:  If the data is worth it, pay the £400.  If not, toss the 
drive.  Or keep it if you like logical puzzles and have time on your hands.
