Hi,
I have a new Thunderbolt 3 OWC SSD external drive that connects to my 2020 Mini's T3 port and even since before I formatted the external (to APFS), I kept getting "Disk Not Ejected Properly"messages as the OWC kept unmounting on its own, even during a clone. I am running Catalina 10.15.3.
I have also experienced a similar issue on Mojave and Catalina with my USB 3.0 OWC HDD external spinning down down at random even when I am working off it. Because I use Pro Tools I disable any options for putting the Mac or display to sleep or automatically ejecting externals. Now I notice on Catalina that when the T3 SSD unmounts and I get the notification, the USB 3 drive flickers a bit.
I have tested multiple cables and ports plus unplugging my T3 audio interface (which still uses its own power supply) suspecting a bus power-power struggle between neighboring peripherals (the T3 SSD does not have its own P.S.). I have also hooked up the Mini's power supply to its own wall outlet instead of a fully populated power strip. But nothing has helped.
Any help in this matter would be highly appreciated! Thank you.
