Meanwhile, searching on the web, I’ve read that to find a “donor” hard disk for head stack “transplant”, model, firmware and the 5th and the 6th chars of the DCM code must match. Others say that the model, the firmware and the last 5 chars of DCM must match, and som others only the last 5 chars of DCM code.
I think there is some confusion due to differents models and codes.
So, if some Western Digital technician could tell me the way to find a “donor” or a list of compatibles models and DCM codes will be really appreciated.
before you jump into considering head replacement, watch this video:
it actually may turn out to be a much simpler issue, and data recovery in this situation is very much guaranteed.
