Seagate ST3320418AS SATA 3.5 PCB (9SL14C-034 / CC45 / 5701 AR) - Logic Board

This sale is for the hard drive PCB / logic board only — no hard drive included. Because we stock a large number of boards, the exact PCB you receive may differ slightly from the photo. This circuit board is intended for use in data recovery or hard drive repair. Before purchasing, confirm that a replacement PCB will resolve your issue by following our hard drive diagnostics guide and verifying compatibility with the Donor Matching Guide. Most Seagate PCBs store unique calibration and configuration data in a ROM "memory" chip; that information is required for the drive to function properly. The ROM chip or its data must be transferred to the replacement board. If the chip can be moved, a local computer technician can typically perform the transplant; for DIY repairs consult our PCB Replacement Guide. For orders of $60 or more we provide a complimentary adaptation service that includes either relocating the ROM chip to the new PCB or reprogramming the board with the correct ROM data. If a simple board swap does not restore your drive, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
