Seagate ST3250318AS 9SL131-542 CC66 5699 V SATA 3.5 PCB (Logic Board)

Product is the hard drive PCB / logic board ONLY — no hard drive is included. Because we maintain a large inventory of PCBs, the exact board you receive may vary slightly from the photo. This circuit board is intended for HDD repair or data recovery work. Before purchasing, confirm that a replacement PCB will solve your issue by following our hard drive diagnostics guide and checking compatibility with the Donor Matching Guide. Most hard drive PCBs contain unique ROM memory chip data that is essential for correct drive operation; the ROM chip or its data must be transferred to the replacement board. If the chip can be physically moved, a local computer technician can typically perform the transplant. For orders of $60 or more we include a complimentary adaptation service which covers either moving the ROM chip onto the new PCB or reprogramming the replacement board with the proper ROM data. If you plan to do the swap yourself, review our PCB Replacement Guide first. In cases where a simple board swap does not resolve the problem, we offer a dedicated PCB Replacement Service — visit the Adaptation Service page for full details.
