Seagate ST31500341AS SD1B 9JU138-259 100530699 E — SATA 3.5 PCB Only

This listing is for the hard drive printed circuit board (PCB / logic board) ONLY — no drive is included. Because we stock a large quantity of these PCBs, the exact board you receive may differ slightly from the photo. These boards are supplied for HDD repair and data-recovery work. Before purchasing, confirm that a replacement PCB is the appropriate fix by consulting our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Most Seagate PCBs store critical, drive-specific information in the ROM memory chip; that data is required for correct operation and must be transferred or programmed onto the replacement board. If you cannot transfer the ROM chip yourself, a local computer technician can usually perform the task. For customers spending $60 or more, we provide a complimentary adaptation service — either moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If a straight board swap does not resolve the problem, we also offer a dedicated PCB Replacement Service; see the Adaptation Service page for full details and options.
