WD30EZRS-00J99B0 / 2061-771698-904 AC - WD SATA 3.5 PCB (Logic Board Only)

This sale is for the hard drive PCB (logic board) only — no hard drive included. Part numbers: WD30EZRS-00J99B0 and 2061-771698-904 AC; SATA 3.5 form factor. Because we carry a large inventory, the actual PCB you receive may differ slightly from the photo. Intended use: data recovery and hard drive repairs. Before buying, confirm that a replacement PCB will address your problem by consulting our Hard Drive Diagnostics Guide, and verify compatibility using the Donor Matching Guide. Important: many HDD circuit boards store unique drive configuration in a ROM "memory" chip; that information is required for correct operation. The ROM contents must be transferred to the replacement board or the replacement must be reprogrammed with the correct ROM data. If transferring the chip is possible, a local computer technician can typically perform the swap. For purchases of $60 or more we include complimentary adaptation service, which covers either transplanting the ROM chip onto the new PCB or reprogramming the new board with the proper ROM data. If you prefer to do the work yourself, review our PCB Replacement Guide first. In situations where a simple board swap does not resolve the issue, we offer a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
