WD SATA 3.5 PCB - WD2500AAKX-00U6AA0 / 771640-103 AC

This listing is for the hard drive printed circuit board (PCB / logic board) ONLY — the hard drive itself is NOT included. Item pictured may differ slightly from the board you receive due to available stock variations. Designed for use in data recovery and HDD repair scenarios.\n\nImportant compatibility and installation notes: verify that this PCB is compatible with your drive by consulting our Donor Matching Guide. Many drive PCBs store critical, drive-specific data in a ROM (memory) chip; that ROM contents are required for the drive to function correctly. The ROM chip or its data must be transferred to the replacement board. If the chip can be physically relocated, a local computer technician should be able to perform the transfer.\n\nServices and support: for purchases of $60.00 or more we provide a complimentary adaptation service, which includes either transplanting the ROM chip onto the replacement PCB or reprogramming the new board with the correct ROM data. If you plan to do the swap yourself, please review our PCB Replacement Guide before starting.\n\nIf swapping the circuit board alone does not resolve the problem, we also offer a comprehensive PCB Replacement Service to handle more complex cases — see the Adaptation Service page for full details.
