External Drives STILL ejecting during sleep in Ventura

Until there's a solution to the problem do what I do, don't sleep the Mac. Just set the Energy Saver settings pane like this:

SSD's don't need to be slept so just activate the screen saver.

Actually that didn't fix the issue for me. You have to totally prevent the computer from sleeping. That is found under Display settings, Advanced options.

Same thing happening to me. Disk not properly ejected message on my External SSD!

Always after sleep mode. In the new system, they removed the option of energy saver, where it was possible to put the hard disk so it doesn't turn off after sleep.

Apple complicating things simple again!

Here’s the thing:

When the machine goes to sleep; external drives will be ejected.

So there are two approaches macOS could take:

1) Have the OS eject all externals before going to sleep. This is perhaps the safest approach rather than complain that the drives were improperly ejected, but the OS would need to try and auto mount the drives again upon awakening.

2) Don’t sleep the machine if there are external drives mounted. This is perhaps the more obvious thing to do, but it’s inevitable people would complain their devices aren’t sleeping when idle.

It’s unclear which approach is better, though I can certainly see people complaining that their laptops won’t sleep because they forgot they had a USB key mounted.

Here is what I found in Ventura, as per your request to look.

System preferences/Displays/Advanced

Under battery & Energy

There is a statement: "Prevent automatic sleeping on the power adapter when the display is off" Not sure if this has anything to do with the problem.

I have found now that I repeatedly receive the Disk Not Ejected Properly, every few minutes now for both external drives. This is most irritating. This has been happening now for two days.

Message:

"Disk Not Ejected Properly" Eject "DriveName" before disconnecting or turning it off. This message is automatic, I have tried everything I know, but so far unable to stop it.

Apple should be taking responsibility for such situations. Unforteunately customer support has in the past not been very helpful with other situations, but I will be attempting to use them again.

MacBookPro9,2. Why fix it if it ain't broke? Apple is rich enough without more of my money. Try waking the machine up by random stroking and tapping the track pad, and see if it ejects your drives. This problem seems universal, given all these reports, so it has nothing to do with the age of my machine.

BTW: Just to be clear on something: the problem often manifests itself (becomes apparent to you) when the machine is awakened from sleep, so it is logical to think it is sleep-related, but on occasion over the years I've had disks eject when the machine is awake and I'm actively using it. I've never drawn any conclusive connection between what I was doing at the time and the ejection, since I could never repeat the problem, but now I am very suspicious of that track pad interface, perhaps even some esoteric keystroke combination, particulary because none of the highly technical solutions offered by Apple or the community have solved the problem. Apparently random software problems, which are never really random, are the hardest to troubleshoot unless they can be duplicated.

My Mac sleeps, I just have it set to not put drives to sleep.

It is connected to a TV as a monitor which has its own sleep function. When the Mac goes to sleep, the display turns off after about five minutes of no signal.

I primary have it set not to sleep the drives because I don’t want to wait for every drive to spin up Whalen I open or save a file.

Spoiler alert: alas, my theory that track-pad events were causing ejects is not valid. This A.M. 4 of my 7 external drives, one an SSD, the other a mechanical, were ejected when I awakened the machine. So, back to the drawing board. Does anyone know the exact log file that High Sierra writes when such events occur? Since only 4 drives were ejected I intend to focus on their enclosures (USB bus powered) and initiate a new dialogue with vendor (Other World Computing). Interestingly, both drives participated last night in uneventful backup events, which means CCC woke the machine, then woke the drives (each drive has two partitions, thus 4 logicals), performed the backups and then, after backups finished, the machine returned to sleep. I smell a big Apple rat, er bug, or some timing issue with the enclosures' power management circuit in conflict with an OS wake up signal. Logically, any cached data should have flushed before backup, so probably no loss of data. Nothing more tragic than powering off a sleeping drive, but still very annoying.

Tried this setting with 13.1, and yes, no drives were ejected. But I had a t least one incident where an external drive was not properly mounted (drive was visible on the io-port).

Now on drive eject issues - what has the setting from above to do with drive ejects? Regardless of being connected to a power adapter or not, my MBP did eject drives.

I might turn that setting off, just to see if the issue appears again. And hope it does get resolved by Turing the setting on again ;)

oh well, back to square one......Did update to Ventura 13.2.1 - and guess what

Disc eject is back...

The only other change was to update Adobe software Lightroom, Lightroom classic and ACR to the latest versions.

No settings change, all look the same a s before.

perlboy_emeritus, I agree with you that Apple is not user-friendly with any other product not made by them. I have had my own story about Apple.

They are even challenged with supporting customers with Apple products.

They have some internal procedures and policies that are not even logical, like when I was locked out of a recently purchased Apple laptop being the first owner, and fully registered for Customer Care support. They were not allowed to grant me access to my computer, even with them fully aware of who I was and all the details. Even the supervisor, nope... Apple policy and procedures--wait two or more weeks. A computer system randomly decides this. I had a hard time believing that.

What I did to solve my problem is to take the two external drives over to my Linux computer and checked the hard drives, to clean things up and both work now on my Mac laptop. Plus, I no longer leave them on or attached until needed.

maybe this is the reason they removed the option to auto sleep in desktop macs, this eliminates this problem for once, but, then the planet "will suffer" from this feature as no desktop mac will auto go to sleep at night.

SSDs also are ejecting on my new mac mini m2, but randomly. during regular use. they appear to have not actually ejected. the only thing i notice is the notification telling me they've been ejected improperly. kind of annoying...
