I have a Seagate 1TB HDD ST1000DM003 with a fried PCB board. After doing some googling I found the website http:// . On this website when I look for the PCB board 100762568 it tells me that I should do this ST1000DM003 Seagate PCB 100717520 REV B (Order this one if your HDD model is ST1000DM003) . What I would like to know is if this would work. Will the firmware be correct and allow the PCB board to work? Or will I have to replace the BIOS chip from the original board?
