Apple Mac mini m4 error: Disk Not Ejected Properly.

I have this reoccurring error that happens whenever I wake up my MacMini m4 from sleep. I have read many existing threads on this problem, and nothing seems to be relevant, such as reboot your iPhone (yes that was one of them), a bad hub, drive, cable, etc etc. Some of the questions regarding this error go back 5 years, so it is possibly an intermittent issue.

I'm running a brand new MacMini M4 with everything else also brand new. The device giving me the error is an OWC Express 1M2 (bus-powered) NVMe external drive enclosure with a Kingston 4TB SSD inside, and a certified Thunderbolt 4 cable (also tried a non-certified cable without luck, and a different brand of external drive enclosure).

The OWC is directly connected to one of the 3 TB4 ports on the rear of the MM-M4, so there are no 'hubs' involved.

As I sit here, I have 8 copies of the error message on screen (and this time, that's all there is), but I have had as many as 40 to 50 iterations. Unfortunately there is no 'clear all' option available (that I know of), so I have to click on each one to get rid of them, but the drive itself is still not visible, so I have nothing to click on, even after all the error messages are gone.

If I reboot or restart, the drive appears for a couple of seconds, then disappears just before the stream of error messages appears.

NOTE: Also, an old Samsung 1TB is still visible as a valid drive even after it has been ejected and physically been removed (which is totally illogical).

There is also a 1TB SSD used as a backup drive which appears to be OK.

Another possible issue is the drive light is ON continuously (at present). I would assume it would only be lit during data transfer, but I may be wrong.

Is there anyone that has successfully fixed this error (please no 'suggestions' that are untested). I need a working solution please...
