Seagate ST3500630NS / 9BL146-036 / 3BKH / 100419004 B — SATA 3.5 PCB (Logic Board)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no drive is included. Models covered: ST3500630NS, 9BL146-036, 3BKH, 100419004 B (Seagate SATA 3.5 PCB). Because we have a large inventory, the exact board you receive may look slightly different than the photo. These PCBs are intended for hard drive repair and data recovery work. Before ordering, confirm the part will solve your problem by following our hard drive diagnostics guide and checking compatibility with the Donor Matching Guide. Note that most hard drive PCBs contain drive-specific information stored in a ROM “memory” chip; that data is required for the drive to function. The ROM chip itself, or its contents, must be transferred to the replacement board (or the new board must be reprogrammed with the correct ROM data). If the ROM chip can be physically moved, a local computer technician can usually perform the transplant. For customers spending $60 or more we provide a complimentary adaptation service that includes either moving the ROM chip to the new PCB or reprogramming the replacement board with the proper ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide. If a simple board swap does not resolve the issue, we also offer a specialized PCB Replacement Service — see the Adaptation Service page for more information.
