WD800JD-75MSA3 / 2061-701335-E00 AG — WD SATA 3.5 PCB (Logic Board Only)

This listing is for the hard drive circuit board (PCB / logic board) only — no HDD is included. Part numbers: WD800JD-75MSA3, 2061-701335-E00 AG; fits WD SATA 3.5 drives. Because we stock large quantities, the exact board you receive may differ slightly from the photo. Intended use: data recovery or hard drive repair. Before purchasing, confirm that a PCB swap will resolve your issue by following our hard drive diagnostics guide, and verify compatibility using the Donor Matching Guide. Many WD PCBs store unique calibration and service data in the ROM ("memory") chip; that data is required for the drive to function correctly. The ROM chip or its contents must be moved to the replacement board or reprogrammed onto it. If physical transfer is possible, a local electronics/PC technician can usually perform the chip transplant. For orders of $60 or more we provide a complimentary adaptation service that either relocates the ROM chip to the new PCB or programs the replacement board with the correct ROM data. If you plan to perform the replacement yourself, please consult our PCB Replacement Guide first. If a basic board swap does not restore the drive, we also offer a comprehensive PCB Replacement Service — see the Adaptation Service page for full details.
