Seagate ST3500630NS / 9BL146-503 (3.AEK, 100419004 C) SATA 3.5 PCB — Logic Board Only

Product is the hard drive printed circuit board (PCB / logic board) only — the hard drive itself is NOT included. Because we have a large stock of PCBs, the exact board you receive may differ slightly from the photo. This replacement board is supplied for hard drive repair and data recovery applications. Before purchasing, follow our hard drive diagnostics guide to confirm a PCB swap will resolve your issue, and consult the Donor Matching Guide to verify compatibility. Most modern drive PCBs store unique configuration data in a ROM memory chip that is essential for correct operation; that ROM or its data must be moved or programmed onto the replacement board. If you cannot perform the transfer yourself, a local computer technician can typically transplant the ROM chip. For customers spending $60 or more, we provide a complimentary adaptation service — either transplanting the ROM chip onto the new PCB or reprogramming the new board with the correct ROM data. If a simple PCB change does not fix the drive, we also offer a comprehensive PCB Replacement Service. See the Adaptation Service page for full details and instructions, and review our PCB Replacement Guide if you plan to perform the work yourself.
