Seagate ST3500630AS SATA 3.5 PCB — 9BJ146-033 / 3.ADG / 100406528 C1

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we carry a large inventory of PCBs, the actual board you receive may differ slightly from the photo. Intended use: data recovery or hard drive repair. To confirm whether a replacement PCB will resolve your drive problem, please consult our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Important: many hard drive PCBs contain unique ROM (memory) data required for correct operation. That ROM data or the ROM chip itself must be transferred or reprogrammed onto the replacement board. If the ROM chip can be moved, a local computer technician can usually perform the transfer. For customers who spend $60 or more we include a complimentary adaptation service, which covers 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 yourself, review our PCB Replacement Guide first. If a simple board swap does not fix the drive, we also provide a dedicated PCB Replacement Service — see the Adaptation Service page for details.
