WD30EZRS-00J99B0 / 2061-771698-802 05PD3 — WD SATA 3.5 PCB (Logic Board Only)

This sale is for the hard drive circuit board (PCB / logic board) ONLY — no hard drive included. Compatible with WD30EZRS-00J99B0 and 2061-771698-802 05PD3 SATA 3.5 drives. Because we stock large quantities of PCBs, the exact board you receive may differ slightly from the photo. Intended primarily for hard drive repair and data recovery tasks. Before purchasing, verify whether a replacement PCB will resolve your issue by consulting our hard drive diagnostics guide, and confirm part compatibility using the Donor Matching Guide. Many PCBs contain unique data stored in a ROM "memory" chip that is required for the drive to function correctly; that ROM or its contents must be transferred to the replacement board. If the ROM chip can be physically moved, a local computer professional can usually perform that procedure. For orders of $60 or more we provide a complimentary adaptation service — either transplanting the ROM chip onto the new board or reprogramming the replacement PCB with the correct ROM data. If you plan to do the work yourself, review our PCB Replacement Guide first. If a simple board swap does not fix the problem, we also offer a Special PCB Replacement Service to handle more complex cases — see the Adaptation Service page for details.
