Seagate ST31500541AS 9JU138-302 CC1H 100530699 A SATA 3.5 PCB

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Compatible with Seagate ST31500541AS (9JU138-302, CC1H, 100530699 A) SATA 3.5 models. Because we maintain a large inventory of PCBs, the exact board you receive may differ slightly from the photo. Intended use: data recovery and HDD repair. Before purchasing, verify that a replacement PCB will resolve your issue by following our hard drive diagnostics guide and confirm compatibility using the Donor Matching Guide. Many Seagate PCBs store unique drive-specific data in the ROM (the ROM or “memory” chip). That information is required for correct operation, so the ROM chip or its data must be transferred to the replacement board. If transplanting the chip is feasible, a local computer technician can typically perform the transfer. For customers spending $60 or more, we include a complimentary adaptation service that either moves the ROM chip onto the new PCB or reprograms the replacement board with the proper ROM data. If you plan to do the work yourself, consult our PCB Replacement Guide. Should a simple board swap not resolve the problem, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for details.
