WD30EZRX-00AZ6B0 / 2061-771716-201 AD - WD 3.5" SATA PCB (Logic Board)

This listing is for a hard drive circuit board (PCB, logic board) ONLY — no hard drive is included. Because we have large quantities in stock, the exact PCB you receive may differ slightly from the photo. Use: These replacement PCBs are intended for hard drive repair and data recovery tasks. Before ordering, verify that a board swap is likely to fix your unit by following our hard drive diagnostics guidance. Confirm compatibility by consulting the Donor Matching Guide. Important technical note: Many WD PCBs contain unique ROM "memory" data that is required for the drive to operate correctly. That ROM contents must be transferred to the replacement board or the new board must be reprogrammed with the correct ROM data. If the ROM chip can be physically moved, a local electronics or computer technician can usually perform the transplant. Services we offer: For orders of $60 or more we provide a complimentary adaptation service — either relocating the ROM chip to 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. In cases where a simple board exchange does not resolve the issue, we also provide a full PCB Replacement Service; see the Adaptation Service page for details.
