Why is my Crucial SSD showing "Ejection Warnings" on MacBook Air?

The last two days I've returned to my computer for the first time, I've been greeted by a long list--roughly 30 today, a similar amount yesterday--of "Disk Not Ejected Properly" warnings along the right margin of my screen.

I have no idea where to start looking as the source of this problem. (I will be writing to Crucial.)

This is a new drive (Crucial X9). I have a MaBook Air running Sequoia 15.3.2.

In an ideal world, all manufacturers follow the same common standards correctly and this would never happen. In practice, results are mixed. There may be some dependance on setup and configuration on an individual Mac. If the drive is new and has NEVER worked properly, there might be firmware update needed. One thing you can do is under the Battery Settings, select Options and set it so the laptop never sleeps when on power adaptor. Either Apple or the SSD are not handling the combination of computer and SSD sleeping so one approach is simply to disable that sleep. I would also avoid using the manufacturer drive firmware/software/utilities because those are sometime incompatible with the MacOS.

There have been a lot of reports of Silicon Macs reporting ejection of drives while sleeping. An easy workaround is the following:

1 - shut down the MBA at night. It doesn't take long for a boot so it's not an inconvenience.

2 - if leaving the premises shut down.

3 - if you leave the MBA for any length of time, like a hour or more shut it down.

4 - do not sleep the MBA but use the screensaver: have it go on after a predetermined time and then go black again after a predetermined time.

Thanks. That makes more sense than what Crucial suggested: try a different port; try a different cable; port may need cleaning. (They answered immediately; encouraged me to call back if I still have the problem.)

I have usually just let my MBA go to sleep when I'm not at it. Will Time Machine wake the computer if it is shut down at the time of a scheduled backup? I can always do back ups manually if not. (Currently doing just once a day backups. At night.)

No, Time Machine will not wake a shut down computer but then, there's nothing being changed to backup.

Back again. Regarding your fourth item, I think I've done it, but am uncertain. (The wording of the options are obscure to me.) Could you tell me exactly what I should have done? Thanks.
