Western Digital PCB-WD20EARS-22MVWB0 is a replacement hard drive printed circuit board in Computer Accessories, SKU sku-324780907 and UPC 641676749802. The listing identifies board 771698-802 08P for WD 3.5-inch SATA drives. It is for data recovery or repair; no hard drive is included, and the board received may differ slightly from the photo.

Before ordering, use the seller's diagnostics and donor matching guides to check whether a PCB swap will address the problem and whether the board is compatible. Most hard drive PCBs store unique data in a ROM memory chip that must be transferred to the replacement board or reprogrammed for the drive to work. A local computer technician can usually transfer a movable chip.

For purchases of $60 or more, the seller offers a complimentary adaptation service to transplant the ROM chip or program its data onto the replacement board. The seller also provides a PCB replacement guide for self-installation and a full replacement service if a board swap alone does not solve the problem.
