Seagate ST3500312CS SATA 3.5 PCB - 9GW132-191 SC13 5701 AJ

Hard drive circuit board (PCB / Logic board) ONLY — no hard drive included. Due to the large quantity of PCBs we stock, the exact board you receive may vary slightly from the photo. This PCB is intended for hard drive repair and data recovery work. To ensure a replacement board will resolve your issue, follow our hard drive diagnostics guide and confirm part compatibility using the Donor Matching Guide. Note: most hard drive circuit boards contain unique information stored in a ROM "memory" chip; that data is required for correct drive operation. The ROM chip or its contents must be transferred to the replacement PCB — if the chip can be moved, a local computer technician can usually perform the transplant. For purchases of $60 or more we include a complimentary adaptation service that either moves the ROM chip to the new board or reprograms the replacement PCB with the correct ROM data. If you plan to perform the swap yourself, consult our PCB Replacement Guide. If a simple board swap does not fix the problem, we offer a full PCB Replacement Service — see the Adaptation Service page for more information.
