Seagate ST3500630AS SATA 3.5 PCB — 9BJ146-561 / 3.AAE / 100406528 C

This sale is for the hard drive circuit board (PCB / logic board) only — the hard drive is NOT included. Model: Seagate ST3500630AS. Part identifiers: 9BJ146-561, 3.AAE, 100406528 C. Note: We stock a large number of compatible PCBs, so the exact board you receive may look slightly different from the photo. These replacement PCBs are intended for use in hard drive repair and data recovery situations. To confirm whether a PCB swap will resolve your issue, please consult our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Important: Many Seagate PCBs store unique configuration in a ROM memory chip that is required for correct drive operation. That ROM chip—or its data—must be transferred to the replacement board, or the new board must be programmed with the correct ROM contents. If physical transfer of the chip is possible, a qualified local technician can typically perform the transplant. Services: For orders of $60 or more we include a complimentary adaptation service, which covers moving the ROM chip to the replacement PCB or reprogramming the board with the proper ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide first. Should a simple PCB change not fix the drive, we also offer a full PCB Replacement Service — see the Adaptation Service page for more information.
