Had to reinstall software. Get a message Upgrade to WD SmartWare Pro by selecting Activate. Selecting Activate does nothing.
You could refer to the following link: https://support-en.wd.com/app/answers/detail/a_id/9336
The link says WD Smartware can no longer be upgraded to WD Smartware Pro. but Western Digital has left the upgrade in the software. The solution is to ignore the WD Smartware Pro upgrade notice.
