I have a Seagate Barracuda ST1000DM003 and am looking for a replacement PCB. The PCB in the drive now is 100664987 REV B. Do you have one available?
https://www.hddzone.com/st1500dm003-seagate-pcb-100664987-rev-a-p-710.html is your donor PCB.
When you get this PCB, you need to move your original PCB’s BIOS to the replacement PCB. The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS.
