Seagate ST3750640NS SATA 3.5 PCB - 9BL148-080 (3.AEJ / 100409233 E)

This sale is for the Seagate ST3750640NS hard drive circuit board (PCB / logic board) ONLY — no drive is included. The board corresponds to 9BL148-080, version 3.AEJ, with marking 100409233 E. Because we stock a large number of PCBs, the actual board you receive may differ slightly from the photo. Intended use: data recovery and hard drive repair. Before purchasing, verify compatibility by following our Donor Matching Guide and run through the hard drive diagnostics guide to confirm a PCB swap is appropriate. Important: most hard drive PCBs hold unique data in the ROM "memory" chip, which is required for proper operation. The ROM chip — or its stored data — must be transferred to the replacement board. If the chip can be physically moved, a local computer technician should be able to perform the transfer. For customers who spend $60 or more, we provide a complimentary adaptation service that includes 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 repair yourself, review our PCB Replacement Guide first. Should a simple board swap not resolve the issue, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
