WD2500JS-40TGB0 2061-701335-100 AD — WD SATA 3.5 PCB (Logic Board Only)

This listing includes only the hard drive circuit board (PCB / logic board). No hard drive is included. Because we stock many PCB units, the exact board you receive may look slightly different from the photo. Designed for hard drive repair and data recovery work, this PCB is intended as a replacement part — however, a swap does not always guarantee a working drive. Follow our Hard Drive Diagnostics Guide to confirm whether a PCB replacement is likely to resolve your issue, and consult the Donor Matching Guide to verify compatibility before purchasing. Most WD PCBs store unique settings in a ROM "memory" chip that is essential for proper operation; that ROM or its data must be transferred to the new circuit board. If you cannot perform the transfer yourself, a local computer technician can usually move the chip. For customers spending $60 or more, we provide a complimentary adaptation service that either transfers the ROM chip to the replacement PCB or programs the new board with the correct ROM data. If a simple board swap does not fix the problem, we also offer a full PCB Replacement Service — see the Adaptation Service page for details and next steps.
