Seagate ST3500418AS (9SL142-240, AP73, 8265 H) SATA 3.5 PCB

Listing is for the hard drive PCB / logic board ONLY — no hard drive is included. We maintain a large inventory of PCBs, so the exact board you receive may vary slightly from the photo. This replacement circuit board is intended for hard drive repair and data recovery use. To confirm a PCB swap will resolve your problem, please follow our hard drive diagnostics guide and check compatibility with the Donor Matching Guide. Many hard drive PCBs contain unique configuration data stored in a ROM "memory" chip; that information is required for correct drive operation. The ROM chip or its data must be transferred to the replacement board. If you cannot perform the transfer yourself, a local computer technician should be able to move the chip. For purchases of $60 or more we provide a complimentary adaptation service that includes either transplanting the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the swap on your own, see our PCB Replacement Guide for instructions. In situations where a simple board replacement does not solve the issue, we offer a specialized PCB Replacement Service — visit the Adaptation Service page for more information.
