Seagate ST1000LM035 1RK172-568 SBM3 8691 C SATA 2.5 PCB (Logic Board Only)

This sale includes the hard drive circuit board (PCB / logic board) only — the hard drive itself is NOT included. Compatible with Seagate ST1000LM035 / 1RK172-568 / SBM3 / 8691 C configurations. Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. Intended for use in hard drive repair and data recovery efforts. Before purchasing, confirm that a PCB swap will resolve your issue by following our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Important: many PCBs contain unique data stored in the ROM ("memory") chip that is essential for correct drive operation. That ROM chip or its contents must be transferred to the replacement board. If you cannot relocate the chip yourself, a qualified local computer technician can perform the transfer. For customers spending $60 or more, we provide a complimentary adaptation service that will either transplant the ROM chip onto the new PCB or reprogram the replacement board with the correct ROM data. If you plan to perform the swap on your own, please review our PCB Replacement Guide first. Should a straightforward PCB replacement not resolve the problem, we also offer a special PCB Replacement Service — see the Adaptation Service page for full details.
