Time Machine won't eject, but all other external discs do

What exactly happens when the TM Backup drive is being ejected ?

Is there an error message ?

Is TM Backup set to a Schedule and you are trying to eject while it is attempting to perform a Schedule Backup.

Aside and perhaps worthy of your attention " I use MacOS 13.5.1 on a 2021 M1 MacBook Pro. "

The Current version of Ventura is presently 13.6 and there is as Standalone update for Safari 17

Thank you

Had to ask as some users ( not you ) partition the drive for Multi Purposes and run into this type of issue

Though this type of message " "Time Machine" wasn't ejected because one or more programmes may be using it. " seems to indicate some Third Party Application is causing this specific error message

Back in OS X 10.4 Tiger when I first stated on Apple Machines I was not away that AntiVirus Software was totally not needed.

When I tried to do certain things on an External Drive would be similar error message

Removed the Garbage AV software and problem solved

Question if I may ?

The TM Backup Drive is a Single Partitioned Drive and used solely for and dedicated Only to Time Machine Backup purposes ?

TM Backup Utility wants the Control the Entire Drive .
