When my external HDD (USB 3.1, Gen 1) is plugged into the hub in the back of my 27" Studio Display I get a notification when waking from sleep that it was ejected improperly. I don't have this problem when this ext. HDD is connected to a stand-alone (powered) hub or the back of my Mac Studio.
Is this normal or, if not, is there a setting I need to make, or do I have a hardware issue here?
Studio Display
Your HDD may be needing more current than the USB port can provide. That is why a powered hub works better. You cannot change any setting that will up the current available at the port on the display. I have found certain SSD's in different enclosures can be powered by the display port and others cannot.

Disable Sleep, it’s unnecessary on later Macs, all pain, no gain. To disable, set your Energy Saver settings to as shown:
Separately, avoid manual sleep, use screen lock instead or let the display switch off/auto-lock on timer. For long or overnight absences, shut.
Can the USB Hub in the 27" Studio Display be used for HDD/SDDs?
