WD7502AAEX-00Y9A0 / 2061-771702-101 AH — WD SATA 3.5 PCB (Circuit Board Only)

This listing is for the hard drive PCB (logic/circuit board) only — no hard drive is included. The item fits model WD7502AAEX-00Y9A0 and PCB 2061-771702-101 AH for WD 3.5" SATA drives. Because we stock large quantities, the actual circuit board you receive may differ slightly from the photo. Intended use: data recovery or HDD repair. To confirm a replacement PCB will resolve your issue, please follow our hard drive diagnostics guide and verify compatibility using the Donor Matching Guide. Important technical note: most hard drive PCBs contain unique calibration and configuration data stored in a ROM "memory" chip; this information is required for the drive to function. The ROM chip or its data must be transferred to the replacement board (or the new board reprogrammed) for proper operation. If the ROM chip can be physically moved, a local computer technician can usually perform the task. For customers spending $60 or more, we provide a complimentary adaptation service that covers transferring the ROM chip or reprogramming the new PCB with the correct ROM data. If you plan to perform the swap yourself, review our PCB Replacement Guide first. If a simple board swap does not fix the drive, we also offer a specialized PCB Replacement Service — see the Adaptation Service page for full details.
