Change PCB of WD40E31X 4.0TB

I have searched a PCB circuit board for WD40E31X but haven’t found anything. Does anyone know where I can buy one? Thanks in advanced

WD does not sell individual/spare circuit boards. I’d recommend browsing online for dedicated hard drive scrap vendors.

unfortunatelly i cannot find 2060-800021-001 circuit board! Propably because it is a quite fresh model. Does anyone know a place which sales this type of cyrcuit board?
