Seagate ST31000340NS SATA 3.5 PCB — 9CA158-145, SU13, 100468979 L

This listing is for the hard drive printed circuit board (PCB / logic board) ONLY — the hard drive itself is not included. Because we maintain a large inventory, the actual PCB you receive may vary slightly from the pictured item. This board is intended for hard drive repair and data recovery use. Before attempting a swap, follow our hard drive diagnostics guide to confirm a PCB replacement is likely to fix the problem, and consult the Donor Matching Guide to verify compatibility. Many Seagate PCBs contain unique drive parameters stored in the ROM "memory" chip; that information is required for the drive to operate correctly. The ROM chip, or its data, must be transferred to the replacement board. If the chip can be moved, a local computer technician can typically perform the transplant. For customers with purchases of $60 or more, we provide a complimentary adaptation service that includes either moving the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the replacement yourself, review our PCB Replacement Guide first. In situations where a simple board swap does not resolve the issue, we offer a specialized PCB Replacement Service — see the Adaptation Service page for full details.
