Q: External Drives Not Sleeping

I'm having issues with my 3 external Hard Drives (1 LaCie connected via Thunderbolt and 2 WD connected via USB) not going to sleep and constantly running.  All websites have said to go to Energy Saver in the settings and ensure Put Hard Drives to Sleep When Possible is selected.  It is selected, but they do not go to sleep.

I've looked all over, but can't seem to find out how to fix it.  Any help or advice would be greatly appreciated.

I'm working with macOS Sierra on a late 2013 iMac.
