Seagate ST3160815AS SATA 3.5 PCB — 9CY132-505 / 3.AAC / 100439890 F

This listing is for the hard drive circuit board (PCB / Logic board) only — no hard drive is included. Because we stock a large number of boards, the exact PCB you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Before purchasing, confirm that a replacement PCB will resolve your issue by following our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Important: most drive PCBs store unique information in a ROM "memory" chip that is required for the drive to operate correctly. That ROM 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 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 first. When a simple circuit board swap does not fix the problem, we also offer a dedicated PCB Replacement Service to handle the more complex cases — see the Adaptation Service page for full details.
