External Drives STILL ejecting during sleep in Ventura

My M1 mini sleeps all the time. I’ve got a couple Thunderbay disk arrays, and several USB-3 spinning, hard drives connected, and I never have a problem. I don’t allow my drives to sleep, but that’s primarily because I don’t want to wait for them to spin up when I go to open or save a file.

pmset disksleep 0

Would you elaborate on where to add "pmset disksleep 0". It's odd that Ventura shows my external USB-C drive shows ejected, but Time Machine is showing no errors. Igt seems as if Ventura thinks the drive was ejected, but the SSD doesn't care...if that makes sense. I added amphetamine, but ti cannot access the Time Machine partition. It can access my media partition on the same drive so we will see if it helps.

I also am somewhat distressed to see Apple allowing this annoying glitch of our equipment to persist, particularly when our Time Machine's external drive seems to have an ever decreasing lifetime even under more stable conditions.

Another annoyance introduced by my switch from Catalina, to improved security with Ventura, has been that in order to share screen now with Apple helpers the customary invites (to Accept and Agree) are gone, and replaced with a pop-up statement that Apple is happy to share your screen. O good! you think? Then the notification disappears and you wonder why ... so you click around a bit, then it appears and disappears again. What's this false offer? It turns out there's an invisible Option notice which will appear if you know how to request it - by hovering the mouse over some imaginary magic spot - and then finally you can click on the eventually visible Accept or Decline etc. Oh what a helpful skip that feels more like a glitchy delay. I'm very grateful for the effort to be even more helpful, but sorry to say I find the new detour confusing and the original track much simpler and more straight-forward.

What have done your years in Mac OS X and Mac OS was make a folder naming it Networked Drives and dag to right side of the dock! After sleep if it doesn't reconnect a mounted drive I just click to icon in right side folder to auto connect back to share I made and alias

This option was moved to, of all places, the Display settings panel under 'Advanced' at the bottom where it . It makes absolutely no sense for it to be there, you would think that it would be with related settings under 'Energy Saver' which has one setting related to actual power savings and a couple sorta related. There is so little logic involved with the location of the individual settings I find myself googling every time I need to find one. I wish Apple would stop making users play "Whack-a-Mole" trying to find the randomly located settings. And I totally agree with the assessment that the new Settings app is a UI nightmare. Sad what things have come to.

You are problem! The problem old style hard drive had to 'Sleep' the years Windows administration have years have said "Macs are to chatty on the network" and so in Mac OS Time stopped Bonjour! So what is happening is the hard drive doesn't get a ping to wake up from Mac OS anymore! So reboot to clear your cache and try it again to see if you get the error on SMB sense MAX OS Venture use SMB 3 now while windows only products sleep all the time and is waiting for Windows machine to wakie it up (be chatty')! :)

This just stopped happening when I went to catalina. Which to me, seems to prove there is something in OS that is different that those on the ventura/mojave sides we or at least machine I use does not know. I have not gone to ventura. Used to use an app I made to eject on sleep. Every time I try to use High sierra or mojave, the thing comes back. Tried to employ the app and, (Probably has to do with the sleep settings) the machine will wake up during the sleep several times and the app is not triggered in that case so theres a long list of "not ejected properly notifications"

Obviously, need to re-work that.

There's always the option of unplugging them untill needed but more convenient to be able to leave them

Chiming in with the resolve on issue here. I am using a 3rd party usb3, machine older than usb3. If I change drives to go on the other usb ports the problem does not occur. Is it really a resolve? The issue only happens on pre- catalina with the usb hub "fl1100" I will not use ventura for machine as the processor lacks what is required for it. So wont know if ventura re-introduces that.

Found this thread. Figured I'd chime in, as well. Three weeks ago, I upgraded to a 2023 M2 Pro MacBook Pro with Ventura 13.5.1 (from a 2010 i5 with High Sierra). In that time, I have had only two instances when I have woken my MacBook in the morning to find the dreaded “disk not ejected properly” notification on my screen. Obviously, this is still a problem that Apple REALLY needs to fix. When I'm tethered to my desk, I always have an external drive plugged in for my Time Machine backups (an OWC Mercury Elite Pro HDD directly connected to my Mac (no hubs or adapters), if that matters). I'm thinking of playing around with some of the other apps mentioned in this thread (Jettison, Ejectify) to see if they might be good fixes for the issue.

adding to the discussion of the usb bugs on ventura:

same here, started in Mojave (or maybe before that), worse after ventura upgrade and still worse/happening after most recent ventura upgrades (now at 13.5.2 (22G91)) and it continues and happens frequently as drives go missing while it is awake as well.

well known/documented bug for many years in Mac OS, I don't understand why it's not only persisted but gotten worse.

iMac 2020 5K intel

FIXED (for me): I have been struggling with my external hard drive “disk not ejected properly” message for years. It randomly and often disconnects my external hard drive, usually during sleep. I have tried everything, including new drives & new enclosures. The other day, I decided to disconnect an old USB 3 hub I have had plugged into a USB port for years. It worked! No more disconnecting of my external drive! I hope this works for some of you!

I am having a similar problem and also may have some insight and a potential course of action. I have a Mac mini with attached storage and mount the attached HDDs using SMB on my iMac. If I step away for some time and come back only one of the mounted shares remains mounted - out of 6 shares. The one that remains mounted has my Photos.app library and Music.app library on it. The others are just bulk storage.

I am assuming that it remains only because there is an active link to the data on it and the others are unceremoniously unmounted because there is no activity on those shares.

The question is how do I cue macOS to maintain an active link all of the mounted shares? OR make those permanent. Maybe there is a autofs setting?

Or maybe the answer is here

Sounds like a MacOS SMB configuration setting, as you suggest.

In a terminal, tryCode:

sysctl -a | grep net.smb

My guess is it's one of those _deadtimer parameters. Try setting them to zero, one at a time, to see if you can find teh one that matters. To change these:Code:

sudo sysctl net.smb.fs.kern_deadtimer=0

etc.

Make a note of their current value before changing; you can just reset these to their previous values the same way if required.

Another Terminal command you might check out

smbutil smbstat /path/to/mounted/share

after editing sysctl to...

sudo sysctl net.smb.fs.kern_deadtimer=0
net.smb.fs.kern_deadtimer: 60 -> 0

sudo sysctl net.smb.fs.kern_hard_deadtimer=0
net.smb.fs.kern_hard_deadtimer: 600 -> 0

sudo sysctl net.smb.fs.kern_soft_deadtimer=0
net.smb.fs.kern_soft_deadtimer: 30 -> 0

the command...

smbutil smbstat /Volumes/Godzilla

shows this...

Yeah, I have the "prevent automatic sleeping on power adapter when the display is off" setting enabled, still getting the warning about drive not being ejected properly. My Time Machine disk, ofc. Ventura 13.5.2.

This has been happening for a while. I can't tell if it's a hollow warning or if there might be some data corruption, but it makes me question the integrity of Time Machine.

All drives are mounted with the write ahead cache enabled, so it’s possible that the drive could still be writing data after the Mac finishes sending it, but in the case of the Mac going to sleep and the drive being ejected during the cached write, that is probably not a possibility
