Seagate ST3500630NS SATA 3.5 PCB - 9BL146-502 | 3.AEG | 100419004 B

This sale is for the hard drive circuit board (PCB / logic board) only — no hard drive is included. Because we stock a large number of PCBs, the exact board you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Before ordering, confirm that a replacement PCB will resolve your issue by following our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Many Seagate PCBs store unique information in a ROM "memory" chip that is required for correct drive operation; the ROM chip or its data must be transferred to the replacement board. When possible the chip can be physically moved to the new PCB by a local computer technician. For customers spending $60 or more we provide a complimentary adaptation service that covers either transplanting the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the swap yourself, please review our PCB Replacement Guide. Should a simple board swap not fix the problem, we also offer a special PCB Replacement Service — see the Adaptation Service page for full details.
