Seagate ST3750640AS SATA 3.5 PCB - 9BJ148-033 / 3.ADE / 100406531 C

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock a large number of boards, the exact PCB you receive may differ slightly from the photo. Designed for use in hard drive repair and data recovery, this replacement PCB should be used only after confirming compatibility. Please consult our Hard Drive Diagnostics Guide to determine whether a PCB swap will resolve your issue, and verify match criteria using the Donor Matching Guide. Many Seagate PCBs store unique configuration data in a ROM "memory" chip; that ROM content is required for correct drive operation and must be transferred or programmed onto the replacement board. If the ROM chip can be moved, a local computer technician can usually perform the transplant. For orders of $60 or more we include complimentary adaptation service, which covers either physically moving the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the procedure yourself, review our PCB Replacement Guide first. If a simple board swap does not restore the drive, we also provide a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
