Seagate ST3500830A 3.5 IDE PCB / Logic Board — 9BJ036-500, 3.AAC, 100406541 G

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive included. Because we stock a large number of boards, the actual PCB you receive may differ slightly from the photo. Intended for hard drive repair and data recovery, this replacement board can be used only after confirming compatibility. Please consult our hard drive diagnostics guide to determine whether a PCB swap is likely to resolve your issue, and review the Donor Matching Guide to verify part compatibility. Most of these PCBs contain unique information stored in a ROM "memory" chip; that ROM data is required for the drive to function correctly. The ROM chip (or its data) must be moved to the replacement board or programmed into it. If a physical transfer is possible, a local computer technician can typically perform the chip transplant. For customers spending $60 or more, we include a complimentary adaptation service that covers either moving the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If swapping the board alone does not fix the drive, we also provide a specialized PCB Replacement Service to handle more complex issues — see the Adaptation Service page for full details. If you plan to attempt the replacement yourself, review our PCB Replacement Guide before starting.
