This Western Digital PCB-WD6400KMVV-11A27S2 hard drive circuit board, sku-921864893, is listed under Computer Components. UPC: 641020051797. The board is marked 2061-701675-401 AB and is a WD USB 2.5 PCB. This listing includes the PCB, or logic board, only; the hard drive is not included. The board received may differ slightly from the photo. Intended for hard drive repair and data recovery, it requires a compatible donor board. Check the hard drive diagnostics guide to see whether a PCB swap addresses the problem, and use the Donor Matching Guide to check compatibility. Many hard drive PCBs hold drive-specific calibration and configuration data in a ROM memory chip. For the drive to work, that chip or its contents must be transferred or copied to the replacement board. A local computer technician can typically transfer the chip when relocation is possible. For purchases of $60 or more, a complimentary adaptation service transplants the ROM chip or programs the replacement board with the correct ROM data. Review the PCB Replacement Guide before doing the swap yourself. A specialized PCB Replacement Service is also available if a basic board change does not resolve the problem; see the Adaptation Service page.You may also like Western Digital PCB-WD5002ABYS-01B1B0 sku-741974935.
