WD30EZRX-00D8PB0, 771945-101 06R — WD SATA 3.5" PCB (Logic Board Only)

Item is the hard drive circuit board / logic board only for WD30EZRX-00D8PB0 (771945-101 06R). No hard drive is included. Because we maintain a large inventory of PCBs, the exact board shipped may differ slightly from the photo. This PCB is intended for use in hard drive repair or data recovery work. Before ordering, confirm that a replacement board will address your issue by following our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Most hard drive circuit boards contain unique configuration data stored in a ROM "memory" chip; that ROM data is required for correct drive operation. The ROM chip itself or its data must be migrated to the replacement board. If the ROM chip can be physically transferred, a local computer technician can usually perform the transplant. For customers spending $60 or more, we include a complimentary adaptation service: 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 for instructions. If a simple circuit board swap does not restore your drive, we also provide a specialized PCB Replacement Service — see the Adaptation Service page for full details.
