Seagate ST3500418AS SATA 3.5 PCB — 9SL142-024 / HP40 / 5701 AE

This 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. Intended for hard drive repair and data recovery, this replacement PCB can restore functionality in many cases. Before purchasing, confirm that a PCB swap will resolve your issue by following our hard drive diagnostics guide, and verify part compatibility using the Donor Matching Guide. Most boards contain unique ROM “memory” data required for correct drive operation; the ROM chip or its contents must be transferred to the replacement board. If you cannot perform this yourself, a local computer technician can often transplant the chip. For customers spending $60 or more, we provide a complimentary adaptation service that either moves the ROM chip onto the new PCB or reprograms the replacement board with the correct ROM data. If you plan to do the work independently, review our PCB Replacement Guide first. Should a straightforward board swap fail to fix the drive, we also offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
