Seagate ST3320620NS SATA 3.5 PCB (9BL14G-303 / 3.AEK / 100419004 D) - Logic Board Only

This listing is for the hard drive circuit board (PCB / logic board) only — no hard drive is included. Because we maintain a large inventory of PCBs, the exact board you receive may differ slightly from the photo. These replacement PCBs are intended for hard drive repair and data recovery work. Before purchasing, confirm that a PCB swap will solve your issue by following our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Note: most hard drive PCBs contain unique configuration data stored in a ROM 'memory' chip; that data is required for proper drive operation. The ROM chip or its contents must be moved or copied to the replacement board. If you cannot perform the transfer yourself, a local computer technician can often transplant the chip. For customers spending $60 or more we provide a complimentary adaptation service that includes either transplanting 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. Should a simple PCB swap not resolve the problem, we also offer a specialized PCB Replacement Service — see the Adaptation Service page for full details.
