January 7, 2016

Q:  Hello, I have a failed Seagate P/N 9TY146-550, Model ST91000430AS, S/N 9YE0BF74, FW CC9C.  Is it possible to find a logic board for it?  I had a repair shop look at it, and they say the a failed logic board is a distinct possibility. Thanks!

A: Please advise the board number which is etched on the PCB, begin with 100***

Q:  Here’s a pic


A: is your donor PCB. When you get this PCB, you need to move your original PCB’s BIOS to the replacement PCB.

Q: thank you for the information!  Is swapping the board any more involved that just pulling out some screws and unplugging a connector?  How do I go about transferring the BIOS?

A: You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Please refer:  Or you can find an electronics repair shop help you.
