Seagate SATA 2.5 PCB — ST9160821AS / 9S1134-042 / 3.CAE / 100459261 B

This listing includes the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we maintain a large inventory of PCBs, the exact board you receive may vary slightly from the photo. These replacement PCBs are intended for hard drive repair and data recovery tasks. To ensure that swapping the PCB will resolve your issue, follow our hard drive diagnostics guide and confirm compatibility with the Donor Matching Guide. Most hard drive circuit boards contain unique configuration data in a ROM "memory" chip that is required for correct drive operation; the ROM chip or its data must be transferred to the replacement board. If relocation of the chip is possible, a local computer technician can typically perform the transfer. For purchases of $60 or more we provide a complimentary adaptation service, which 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 swap yourself, please review our PCB Replacement Guide. Should a simple board replacement not solve the problem, we also offer a dedicated PCB Replacement Service — visit the Adaptation Service page for more information.
