Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.

To Contact WD for Technical Support

You need to run DLG diag before contacting technical support.

But first, ensure your connections (power, data) are solid to the drive; try a different data cable if you have one.
