On my new iMac with Monterrey, I am getting dismount errors after dragging a USB DRIVE to the trash when I start the computer the next day.
This is the old procedure and have no problem on Big Sur computer when switching that USB Drive between the two for various and assundry reasons.
Has there ben a change such as necessity to dismount from Disk Utility?
iMac, OS X 10.11
There hasn't been a change. See the following (which is current for Monterey) from Connect and use other storage devices with Mac - Apple Support
Eject a storage device
On your Mac, do one of the following:
next to the item’s name.If you can’t eject a storage device, another app or user may be using one or more files on the storage device. See If you can’t eject a disk on Mac because an app is using it and If you can’t eject a disk because another user is using it.
Do not know what happened but I replied to this a couple of hours to ago as the same thing happened opening up this morning. However just got another one.
I was in Time Machine Backup trying to delete some old unwanted files and when I closed out; Cancel; up pops the error message for my backup disk. What is really funny is the icon was still on the desktop and worked properly when double clicked. Just to be sure Ii checked the USB connection and all seemed to be ok/tight. As a final check, I did a restart and the error message did not show up. So, am not really confused as to what is happening.
Also, just to clarify, I only saw the error messages the first two times but totally ASSUMED it was for the USB Drive. Meaning those could have been that I had somehow loosened the USB for my backup and when I checked them reseated it properly as everything SEEMS normal now.

What is odd is that this is periodically saying my backup drive was disconnected improperly but it is still connected and indicates it is working properly as should be. Checking the connection shows it is tight so it must be these USB C connectors.
Never mind on this as the problem is that when I have to turn the monitor to get to the back it pulls on the backup drive connection which is barely long enough for the drive to sit on the desk. This is what going to be trouble down the road for some people especially us who MUST use a USB A-C stick for transfer data between computers as the only connections are on the back of the case.
Make that a self powered USB Hub to avoid any power issues that might pop up is a lot of devices are connected to the same port.
You might consider a USB Hub to avoid moving the Mac.
What is the dismount procedure?
