Seagate ST1000DM003 SATA 3.5 PCB — 9YN162-302 CC4C 5011 E

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. The board fits Seagate ST1000DM003 models and is labeled 9YN162-302, CC4C, 5011 E for the SATA 3.5" lineup. Because we stock large quantities, the actual PCB you receive may differ slightly from the photo. Intended use: data recovery or 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 PCBs store unique calibration and service data in a ROM "memory" chip; that information is required for proper operation. The ROM chip or its data must be transferred to the replacement board. If chip transplant is possible, a local computer technician can usually perform the work. For orders of $60 or more we include a complimentary adaptation service that provides either ROM chip transfer to the new PCB or reprogramming the new board with the correct ROM data. If you plan to do the swap yourself, consult our PCB Replacement Guide. If replacing the board alone does not fix the drive, we also provide a dedicated PCB Replacement Service — see the Adaptation Service page for details.
