Seagate ST31000340SV SATA 3.5 PCB — 9DM158-501 / SV16 / 100468979 L

This listing is for the hard drive PCB (logic board) ONLY — no hard drive is included. Because we carry a large inventory of PCBs, the exact board you receive may vary slightly from the photograph. The board is intended for hard drive repair and data recovery use. Before purchasing, confirm that a replacement PCB will solve your issue by following our hard drive diagnostics guide and verifying compatibility with the Donor Matching Guide. Most Seagate PCBs contain unique information stored in a ROM memory chip that is required for the drive to function correctly; the ROM chip or its data must be transferred to the replacement board. If the ROM chip can be physically moved, a local computer technician should be able to perform the transplant. For orders of $60 or more, we provide a complimentary adaptation service that includes either transferring the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If you prefer to do the work yourself, see our PCB Replacement Guide. If a simple PCB swap does not resolve the problem, we also offer a full PCB Replacement Service — visit the Adaptation Service page for more information.
