I think what Mr.Z Bond 007 was trying to say "Why firmware must be taken into account when finding a matching head"

The answer is you dont need to find an idential firmware in order to replace HDA.

Well, the head map are to be taken into account, if you want the drive to work. Or you can manually "remap the map" if you can Anyway the question is badly posted. Please ask again and tell what do you want to do.
