WD10EZEX-07M2NA0, 771829-005 AA WD SATA 3.5 PCB (Logic Board)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive included. Compatible with models: WD10EZEX-07M2NA0, 771829-005 AA. Because we maintain a large stock, the exact PCB you receive may vary slightly from the photo.\n\nThis PCB is intended for HDD repair and data recovery work. Before purchasing, confirm that a replacement board will resolve your problem by consulting our hard drive diagnostics guide, and verify part compatibility using the Donor Matching Guide.\n\nNote: most hard drive PCBs store unique configuration data on a ROM (memory) chip. That ROM data is required for the drive to operate correctly, so the ROM chip or its contents must be moved to or programmed onto the replacement board. If transplanting the chip is possible, a local computer technician can usually perform the procedure.\n\nWe offer complimentary adaptation service on orders of $60 or more; this includes either transferring the ROM chip to the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to perform the swap yourself, please review our PCB Replacement Guide first.\n\nIf a simple PCB swap does not fix your drive, we provide a full PCB Replacement Service to address more complex issues — see the Adaptation Service page for more information.
