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: https://www.hddzone.com/seagate-100570750-pcb-p-392.html 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: http://www.datarecoveryunion.com/hard-drive-rom-chip-swapreplacement/. Or you can find an electronics repair shop help you.
