Still getting 'disk not ejected properly...etc' macOS Catalina, Big Sur and Monterey Beta.

'disk not ejected properly...etc'

Has anybody ever discovered a reason for this perpetual and repetitive message?

Even though none of the offending disks has been touched.

I used to think it was using a non powered hub or drive, way back in OSX Mavericks, but my current 4TB local drive, USB3 to port on rear of iMac 14,1 - in a powered drive case, connects and disconnects for no reason - untouched by human hand and never actually unmounts

I have had successive OS on various machine/OS combo, since 2007 when I changed to Intel iMac

this began happening randomly at first

Come to think of it Firewire never did this.

**** If I boot the same machine into Linux IT NEVER DISCONNECTS. ****

I come to the conclusion over many macOS and Mac hardwares that it may be a software glitch ?triggered by?????

The other external drive 'LOCAL BKP' never disconnects, also USB3 to rear port unpowered?????

Any sensible suggestions would be welcomed.

iMac 21.5″, 11.4

Sorry can't assist. I did have same issues using firewire though. When I run into that "disk not ejected properly" I set the external aside never to be used again. Just transfer the data on it. Purchase some other external. I understand can be expensive but I will not put up with this issue. Waiting for a fix which never comes.
