Seagate ST31500341AS SATA 3.5 PCB - 9JU138-302 / CC1H / 100530699 E

Product is the hard drive circuit board (PCB / logic board) only — no HDD included. Exact board design may differ from the photos because multiple PCBs are in stock. This PCB is intended for drive repair or data recovery work on Seagate ST31500341AS units. Verify compatibility before purchase by consulting our Donor Matching Guide and following the Hard Drive Diagnostics Guide to confirm a replacement PCB will address your issue. Most hard drive PCBs store unique calibration and service data in a ROM (memory) chip; that ROM content is required for correct drive operation. The ROM chip itself or its data must be transferred to the replacement board. If you cannot move the chip, a local computer technician should be able to perform the transplant or reprogramming. For orders of $60 or more we provide a free adaptation service that covers either transplanting the ROM chip onto the new PCB or reprogramming the replacement board with the proper 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 comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
