"Disk not ejected properly"

Hi all.

 

In late 2014, I got a brandnew iMac 5k bundled with a brandnew Pegasus R6 (6 x 2 TB Toshiba). 

Everything worked flawlessly with Yosemite and El Capitán for more than two years - until I upgraded to firmware version 5.04.0000.61 some months ago. Since then the R6 shows a weird behavior. 

When the Mac goes to sleep (or is being put to sleep), so will the R6. When I wake up the Mac the R6 wakes up as well - but randomly the drive icon won't show up on the desktop and I'll get the "Disk not properly ejected" alert. Then after 30 seconds or so the volume will finally mount.

Needless to say that this is a nightmare.  

Is there a way to downgrade to an earlier firmware version that doesn't cause this behavior - or is there any other thing I could try? Recently upgraded from Mac OS X 10.11.6 to macOS 10.12.6 hoping to get the problem solved, but to no avail.

Any help is greatly appreciated...

Greetings from Germany.
