Seagate ST3500630NS SATA 3.5 PCB — 9BL146-302 / 3.AEG / 100419001 A

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive is included. Because we stock a large quantity of PCBs, the exact board you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Before purchasing, use our Hard Drive Diagnostics Guide to confirm a replacement PCB will address your issue, and check the Donor Matching Guide to verify compatibility. Important: many Seagate PCBs store unique configuration data in a ROM memory chip; that ROM data is required for correct drive operation. The ROM chip or its contents must be transferred to the replacement board. If you do not perform the transfer yourself, a local computer technician can typically move the chip. For customers spending $60 or more, we include complimentary adaptation service — either transplanting the ROM chip onto your new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the swap independently, review our PCB Replacement Guide first. In situations where a simple PCB swap does not restore the drive, we also provide a dedicated PCB Replacement Service. See the Adaptation Service page for full details.
