Seagate ST3500418AS (9SL142-023, HP35, 5701 W) SATA 3.5 PCB - Logic Board

This listing is for the hard drive circuit board (PCB / logic board) ONLY — the hard drive itself is NOT included. Because we stock a large quantity of PCBs, the board you receive may differ slightly from the photo. Intended for hard drive repair or data-recovery use, this replacement PCB is compatible with the listed model identifiers: ST3500418AS, 9SL142-023, HP35, 5701 W (Seagate SATA 3.5). Before purchasing, confirm compatibility by consulting our Donor Matching Guide and follow our hard drive diagnostics guide to verify that a PCB swap will address your issue. Most drive PCBs hold unique information in a ROM memory chip that is required for proper operation. The ROM chip, or its stored data, must be transferred to the replacement board. If the ROM can be moved, a local computer technician can usually perform the chip transplant. For orders of $60 or more we provide a complimentary adaptation service that includes either moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the swap yourself, review our PCB Replacement Guide first. If a simple board exchange does not resolve the problem, we also offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
