Hello,
I use a Mac mini as a Server and have two OWC MiniStacks attached to it. The Ministacks are connected via USB3 and are underneath the Mac mini. The Ministack in the middle started disconnecting randomly and I need to turn it off and back on to get it connected.
The Mac mini is always on and I use the USB drives as Server provided networked disks.
I have Seagate Enterprise Capacity Drives everywhere.
I get the following output in Console:

What is going on?
Failing HDD?
Failing Enclosure?
Screwed up Mac mini?
Thank you very much in advance!
