Remove WD Discovery with the built-in uninstaller

Some third-party apps come with built-in uninstallers. You can either find it via Finder > Applications or through the user interface.

Unfortunately, it's not enough to erase all information from the pre-installed WD Discovery. Therefore, you can further clear the cache, hidden files and logs of the older version. Follow the steps below to clear leftovers of it.

Step 1. Launch Finder, then select Go from the top menu bar. Choose Go to Folder from the drop-down option after that.

Step 2. Click Go after entering /Library into the Go to the folder box.

Step 3. Remove the associated files for the deleted app from each folder in the Library folder, including Saved Application State, Cookies, Application Scripts, Containers, Application Support, Caches, Logs, and Preferences.

After clearing all data of the previous WD Discovery version, you can download a new one and install it. Try working your WD drive with it, is it working now?
