WD20EZRX-00D8PB0 771945-101 06R WD 3.5in SATA PCB (Hard Drive Logic Board Only)

This listing is for the hard drive circuit board (PCB / logic board) ONLY — no HDD is included. The actual PCB you receive may differ slightly from the photo due to our large inventory. Designed for use with Western Digital WD20EZRX-00D8PB0 drives for data recovery and repair. Before purchasing, confirm this replacement will resolve your problem by following our hard drive diagnostics guide and verifying compatibility with the Donor Matching Guide. Important: most hard drive PCBs contain critical information stored in a ROM “memory” chip; that data is required for the drive to operate correctly. The ROM chip itself or its data must be transferred to the replacement board. If the chip can be physically moved, a local computer technician can usually perform the transfer. For customers spending $60 or more, we include a complimentary adaptation service that either moves the ROM chip onto the new PCB or reprograms the replacement board with the correct ROM data. If you prefer to perform the swap yourself, review our PCB Replacement Guide. If a straight board swap does not fix the drive, we also provide a dedicated PCB Replacement Service — visit the Adaptation Service page for full details.
