External Drive Unmounting

I'm trying to erase an external hard drive for use as a Time Machine on a MacBook Air (M2) running MacOS 15.1.1

Disk Utility reports that it cannot unmount the disk - in use by processing 112.

I have followed all of the restart and close all programs etc, advice that is posted, but it makes no difference.

I have the same problem on my M4 Mac Mini.

The external drives have USB A plugs, but as both machines have USB C ports, I am having to use an adapter.
