Seagate ST3600057SS SAS 3.5 PCB — 9FN066-881 / 000B / 100549572 J

This listing is for the hard drive circuit board (PCB / Logic board) ONLY — no hard drive is included. We stock a large quantity of these PCBs, so the item you receive may vary slightly from the photo. Intended for use in hard drive repair or data recovery projects. Before ordering, please consult our hard drive diagnostics guide to confirm a PCB replacement will resolve your issue, and review the Donor Matching Guide to verify compatibility. Many Seagate PCBs store unique configuration data in the ROM "memory" chip; that information is required for the drive to operate correctly. The ROM chip or its saved data must be transferred to the replacement board, or the replacement board must be reprogrammed with the correct ROM contents. If you are unable to perform this yourself, a local computer technician can often move the chip for you. For customers spending $60 or more we include a complimentary adaptation service, which covers either transplanting the ROM chip onto your new PCB or reprogramming the replacement board with the proper ROM data. If you plan to do the work yourself, please read our PCB Replacement Guide first. Should a simple board swap not fix the problem, we also offer a full PCB Replacement Service to handle more complex cases — see the Adaptation Service page for details.
