Seagate ST3500418AS 9SL142-543 CC67 5701 W SATA 3.5 PCB

Listing is for the hard drive circuit board (PCB / logic board) ONLY — No hard drive is included! Because we stock a large quantity of PCBs, the exact board you receive may differ slightly from the photo. This PCB is intended for hard drive repair and data recovery work. Before ordering, confirm that replacing the PCB will resolve your issue by consulting our hard drive diagnostics guide and verify part compatibility using the Donor Matching Guide. Most hard drive circuit boards contain unique data stored in a ROM "memory" chip that is required for the drive to function properly; that ROM chip or its data must be transferred to the replacement board. If the ROM chip can be physically moved, a local computer technician can usually perform the transfer. For customers spending $60 or more, we provide a complimentary adaptation service that includes either moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the swap yourself, review our PCB Replacement Guide. Should a simple board swap not fix the problem, we also offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
