Seagate ST3500312CS SATA 3.5" PCB - 9GW132-291 SC13 5701 T (Hard Drive Logic Board)

This listing is for the hard drive circuit board (PCB / logic board) only — the hard drive itself is NOT included. Because we stock a large number of these PCBs, the exact board you receive may differ slightly from the photo. Designed for repair and data-recovery work, this PCB fits Seagate ST3500312CS units with identifier 9GW132-291, SC13, 5701 T and SATA 3.5" configurations. Before purchasing, confirm compatibility by following our Donor Matching Guide and run the steps in our Hard Drive Diagnostics Guide to determine whether a PCB replacement is likely to resolve your issue. Important: many hard drive PCBs contain unique information stored in a ROM memory chip that is required for the drive to operate correctly. That ROM data must be transferred to the replacement board or the ROM chip physically moved to the new PCB. If you are not doing the transfer yourself, a local computer technician can often perform the chip transplant. For customers spending $60 or more, we provide a complimentary adaptation service that includes either relocating the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide for step-by-step instructions. Should a straightforward board swap fail to fix the problem, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
