Seagate ST3320620NS SATA 3.5 PCB — 9BL14G-302 / 3.AEG / 100419004 A

This listing is for the hard drive circuit board (PCB / logic board) only — the drive itself is not 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 a replacement PCB will address your issue by using our Hard Drive Diagnostics Guide, and verify compatibility via the Donor Matching Guide. Many Seagate PCBs include a unique ROM "memory" chip that contains required parameters for the drive to function. That ROM or its contents must be transferred to the replacement board for proper operation. If the ROM chip can be moved, a local computer technician can typically perform the transplant. For customers spending $60 or more, we provide a complimentary adaptation service that 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 do the swap yourself, review our PCB Replacement Guide first. When a simple PCB swap does not resolve the problem, we also offer a specialized PCB Replacement Service to fully address the issue — see the Adaptation Service page for details.
