Disk not ejected properly

After I eject and disconnect an external drive or a pen drive in my Mac mini running High Sierra, the majority or times appears the following message:

DISK NOT EJECTED PROPERLY

EJECT (DRIVE NAME) BEFORE DISCONNECTING OR TURNING IT OFF.

I never disconnect it before I eject it , but even doing that, the message appears.

What am I doing wrong? Or it's a system bug?

Mac mini, macOS 10.13

Disk not ejected properly Once every few days I get a message saying disk not ejected properly referring to a brand new external drive even though it is not being removed. A quick search suggested running First Aid which didn't help. I tried different a connection cable and a different port on the Mac. No luck. I use the drive exclusively for Time Machine MacBook Pro 2021 Ventura 13.4.1 External drive: LaCie 4 TB, 1.6 GB used Thanks, community!

Disk Not Ejected Properly New MacBook Air w/Ventura 13.4 and external LaCie hard drive for Time Machine. When awakened from sleep 8 or more notifications appear saying: Disk Not Ejected Properly Eject "LaCie" before disconnecting or turning it off. This happens every time whether or not I have ejected the LaCie hard drive. Apple support absolutely no help. They act like they never heard of this issue despite the fact that the forums are full of people with the same issue. This never happened with old MacBook Pro and earlier operating systems. Why hasn't Apple addressed this? Any idea what might be going on?

disk not ejected properly since Ventura I have a 24 inch mac M1 with Ventura 13.1 I have 2 external USB hard drives and 2 SSD drives in a bay connected to the mac. I do not attempt to eject or disconnect them. Since Venture, I have been getting the disk not ejected properly message apparently randomly but sometimes several times a day. Sometimes the message refers to one disk drive, sometimes to 2 drives simultaneously and sometimes to all 4 at once. The message rarely occurred before Ventura but is now quite frequent. I have tried all remedies suggested elsewhere resetting SMC, NVRAM etc but to no avail. I have analysed all disks and applied first aid but as far as I can see, the disk are all aok. Does anyone know if this is a Ventura problem or if there is a way of eliminating the message?

There could be a delay ejecting an external drive or flash drive if it is being used by a macOS process or an App.

I generally wait about 20 to 30 seconds after the drives icon disappears from the Desktop and/or the Finder sidebar before unplugging it.

Than you for your reply. I think you're right, I have to wait to unplug the drive.
