I have a Crucial SSD connected to a Mac mini 2024 M4 running Sequoia 15.3.2. I am continually getting a message Disk Not Ejected Properly when nothing has been done to the SSD at all. Cables are not touched at all and fit snug. Nothing has been moved yet the message comes up as if it has been disconnected. I did open Finder before this happened so I will watch and see if this happens again.
Any ideas?
Mac mini, macOS 15.3
Full Computer Sleep Mode is causing problems including external drive and external display issues.
As a test:
Turn On "Prevent automatic sleeping when display is off"
Set "Turn display off when inactive" to 5 or 10 minutes
Leave the Mac Mini On and only allow the display(s) to turn Off on the timer
Do not manually select Sleep from the Apple Drop Down menu
Only Shut Down the Mac when away for a day or more
It may help, if folks send Feedback.
What model is the Crucial SSD...?
How is the Crucial SSD connected to the Mac mini...?
(rear or front USB-C port) (into a hub)
Have you tried connecting the Crucial SSD to a different Mac mini port...?
It is a Crucial X8 4TB Model CT4000X8SSD9A. I actually did switch to a USB-C port on the front of the Mac mini and so far I have had no problem. I will keep posting if it should reoccur. Thanks for your help!
You're welcome.
So on continuing to monitor the situation, it seems to happen after it has been asleep and upon waking up I get the "Disk Not Ejected Properly Message".
External drive being ejected.
