Every time my Mac mini m4 goes to sleep and awakens, I get a message saying my external hard drive was not ejected properly. I have tried all the suggestions in prior comments. Anyone at Apple working on this issue??

This is more a problem with Sleep, you should turn off sleep and in System Settings please do the following:
This will turn your display off and you should no longer have a problem with the disk ejection.

Open preferences, energy and set the following and be sure you have the screen display turn off from the lock screen pane
+1
Full Computer Sleep Mode is causing external drive, external display and other issues.
As a test:
Turn On "Prevent automatic sleeping when display is off"
Set "Turn display off when inactive" to 5 or 10 minutes
Leave the Mac On and only allow the display(s) to turn Off
Do not manually Sleep from the Apple Drop Down menu
Only Shut Down the Mac when away for a day or more
Don't hold your breath, but it might help if enough folks send Feedback to Apple.
ALMOST SOLVED.
Have had this problem since I bought a Pro Cylinder years ago. Got worse when I bought a new M4 MM. After trying EVERY solution without success on my new M4 MM, I bought a powered hub and connected my keyboard and printer to the hub. (MM does not like the backup drive connected to the hub and flags unending errors.)
MM ran almost a week with an error BUT this morning, the dreaded Disc not ejected properly message showed up again.
Why everything worked for a week; not a clue but maybe someone smarter than me can ponder on the IEEE1284 interface. Another clue, my rock solid VPN died frequently with the M4. Changed the AutoLock setting to off; no more problem. Thoughts?
Have you run Disk Utility's Disk First Aid on all connected drives?
In Disk Utility>View, select Show all Devices, highlight the top left entry.
Run Disk First Aid on all items in the left panel, from top down.
Are you running any VPN, Anti-Virus, or Cleaning apps?
We need to see what all is running, a report from this will not display any personal info...

Perhaps a silly question, but how do I turn off Sleep on my mac mini?
