I have two external WD hard drives permanently connected via USB to a Mac Mini. The Mini is running macOS High Sierra. Every few minutes, one or both of the hard drives reports that it was “not correctly ejected”. A few minutes later it re-appears on the system. The frequency of the supposed ejection is now stopping me from using these drives for anything useful.
I tried downloading the latest ‘WD Drive Utility’ to check these drives out but it does not find either drive.
