Seagate ST9120315AS 9HH131-120 0002CE02 100572173 C SATA 2.5 PCB

This listing is for the hard drive printed circuit board (PCB / logic board) only — no hard drive is included. Because we stock a large number of these boards, the exact PCB you receive may differ slightly from the photo. This PCB is intended for use in data recovery or hard drive repair. Before ordering, confirm compatibility by consulting our Donor Matching Guide and run our Hard Drive Diagnostics Guide to determine whether a replacement board will resolve your issue. Most Seagate PCBs contain critical, drive-specific data stored in a ROM memory chip; that information is required for the drive to function correctly and must be transferred or reprogrammed onto the replacement board. If you cannot transfer the ROM chip yourself, a local computer technician can usually perform the task. For customers who spend $60 or more, we include a complimentary adaptation service, which covers either transplanting the ROM chip onto the new PCB or programming the correct ROM data into the replacement board. If a simple board swap does not fix the problem, we also provide a dedicated PCB Replacement Service — see the Adaptation Service page for full details and the PCB Replacement Guide for step-by-step instructions.
