As posted, the replacment board must be from exactly the same model and
series hard drive. Replacing it is a matter of removing hte mounting
hardware and swapping the physical pc board from the know good drive to the
one in question. Probably 50 - 70- % success in doing so if the antistatic
procedures are followed.

thanks for all the replies,
this is what information I am looking for, is how to replace the
controller board. and where do I find instructions of how to replace the
board. this information is not vital, I just want to see how to fix the
drive or not, but not at the recovery prices from the drive repair places.

thanks to all for the insight.

I have a couple of hard drives that may be good, and only have a bad
controller chip. how do I test and how do I replace or send it to
somebody
who can. thanks

I have been able to buy the same model on e-bay and replace the
controller
bd. Worked fine. Mine was a 30GB Maxtor.
