Why do I get "Disk not ejected properly" error?

I use Disk Utility to eject external SSD or drag to Trash but get "Disk not ejected properly" Notification when I wake from Sleep or Restart. It seems there's no way to avoid this. It's been happening for months while I kept hoping the next OS would fix it. Now it seems to have disabled two external SSDs — a Sandisk 500 GB and a T7 Samsung 500 GB. They show on my Desktop but Time Machine does not recognize them. I've erased them with Disk Utility but problem remains.

MacBook Air 13″, macOS 12.2

Definitely an Apple problem. I was trying to solve another prob ie adjuested setting to stop the mac shutting down if I was away from it for more than 10 mins....so got that to stop but as a result have the same 'Disk not properly eject 'message instead. And its a **** of a lot more annoying than the other prob. Going to reverse through what I changed. But definitely APPLE.

Here's some food for thought: unless you're using a true VPN tunnel, such as between you and your employer, school or bank's servers, they are useless from a privacy standpoint. Read these two articles: Public VPN's are anything but private and Former Malware Distributor Kape Technologies Now Owns ExpressVPN, CyberGhost, Private Internet Access, Zenmate, and a Collection of VPN “Review” Websites.

Also have you installed and run any "cleaning", "optimizing", "speed-up" or anti-virus apps on your Mac? They also should be removed according to the developer's instructions.

When the MacBook (and I) woke from sleep this morning, these were the notifications waiting for me.

Give it another 1-2 weeks and it may return but I hope not.

Updated OS and iOS. Still get "Disk not ejected properly" but less frequently. I just hope it is not damaging my backup SSDs.

THIS SEEMS TO FIX THE PROBLEM

If a Settings change can fix the problem, perhaps Apple can tweak the OS to do the same.
