"Disk not ejected correctly" msg from 2016 MacBook laptop I sometimes use the laptop periodically throughout day without unplugging it or the external drives.  However, if it puts itself to sleep as a result of a period of inactivity, when I reawaken it, I get the message "Disk not ejected correctly"    How can I get rid of this message as I have not removed the disks at all, the data is not corrupted, and I have not told the computer to go to sleep!
If I remember correctly, to completely get rid of the message, you can go to System Preferences -> Energy Saver and uncheck the box that says "Put hard disks to sleep when possible". That will eliminate the message, but it also means that your computer will use more energy and that the hard drives will be on and spinning constantly.

If this doesn't work, let me know. (Disclaimer: It's possible this won't work; I can't remember if "Put hard disks to sleep when possible" works only for internal drives or also for external ones.)
