Disk not ejected properly "Backups of ..." on Ventura

Regretfully unhelpful: this set of "resources" do not appear to have been updated for Ventura. Additionally, these resources do not address the problem reported, which appears as a spontaneous early disconnect of the backup disk and not a failure or inability to connect to the disk.

I still have this with my M2 Pro Mac Mini when backing up to a QNAP NAS using Time Machine, OS & all apps/firmware up to date. Backup will complete if I sit and kerep pressing 'Backup Now', TM still backs up wihout issue to my 2 locally connected USB Drives, 1 via USB-C, 1x USB-3.

For anyone who has been experiencing this problem and has set their Time Machine destination to a Synology NAS product that is still running the legacy Synology DSM 6.x series operating system, there may be a fix (unconfirmed). Synology just released an update that includes the following fixes:

Fixed Issues

1. Fixed an issue where files shared via SMB may not be discoverable through macOS Ventura's Spotlight search.

2. Fixed an issue where files shared via AFP may not be discoverable through macOS Ventura's Spotlight search.

Here is the link to the Synology DSM release notes: https://www.synology.com/en-us/releaseNote/DSM

Again, I have not confirmed that the issue in this thread is addressed by this Synology update. The Spotlight file indexing service may be unrelated to a macOS Ventura machine losing its connection to network based Time Machine store after sleep.

I realize that people who use a Synology 6.x NAS as their Time Machine target may be a narrow audience. I will re-post once I confirm whether this is fixed or not.

The Synology update did not fix this issue. While I only occasionally experience the "disk ejected improperly" error, I did see the error again after updating my Synology 6.x DSM operating system. I have my Time Machine backups on manual and I do not let my MBP sleep while performing a backup. But occasionally upon lid open/wake I will get the error.

I also do Time Machine on a Synology running DSM 7.1.1, and I experience this issue on 3 ventura machines: A MacStudio M1 ultra, a MacBook Pro Intel and a MacBook intel (all upgraded to Ventura 13.3). What is different between the different clients is the amount of messages. On the MacStudio after a night in sleep I normally find between 4 and 8 "Disk not ejected properly" messages. On the other two the messages come out only occasionally

Ventura Version 13.5 (22G74) was released yesterday.

13.5 does not seem to have resolved this. On to 13.6?

Yep, If I constantly restart the network backup it will complete after 15-20 attempts, it then needs to verify this backup, so a previously automated & reliable backup now needs me to pay it 100% attention for a week. So a total showstopper. QNAP are adamant it’s not their NAS, so it’s down to Apple.

I too have been using Time Machine on a Synology for many years and have been suffering from this bug since upgrading to Ventura. Currently, I'm running Ventura 13.3.1 on a MacBook Pro and backing up to Synology NAS running DSM DSM 7.1.1-42962 Update 5. Every time my MacBook goes to sleep, I see the Disk not ejected properly "Backups of ..." message upon resuming. The backups have become very unreliable. For instance, at this moment, when I browse Time Machine Backups, I can only go as far back in time as yesterday. Can't go back any further. It's been over six months since Ventura was released and people reported this problem. Still no fix from Apple?

thanks for the suggestions, but that seems like a lot of bother compared to clicking dismiss on the notifications. It's easy to make them go away; they're just annoying. Hopefully Apple will resolve this quickly.

Interestingly, this problem does not seem to occur on our equally new 14 inch MBP. Both the Mini and the MBP have the same M2 Pro processor.

I can tell you that Ventura 13.4.1 has the same problem. The best part of this conversation is knowing that this is simply an annoyance not a real problem . My Seagate remounts, and life goes on. Someday they will fix it, one hopes.

Oh well we'll see what people say about 13.5; I haven't seen that update notification (and I wonder why....)

To those with Synology backup equipment, you are not alone with the "Disk Not Ejected Properly" problem. I have been doing my Time Machine backups on an AirPort Time Capsule (version 7.9.1) for a long time, and I have now been getting the same message, seemingly since I upgraded to Ventura. I have a 2017 iMac (3.8 Ghz Quad-Core Intel Core i5, for you youngsters) now running Ventura 13.6.1. The "disk eject" message started happening a couple of updates ago. I fear that built-in obsolescence will prevent me from receiving another Ventura update with a solution, since I already can't upgrade to Sonoma with this system. Another Community Specialist or Level 10 solution won't help me much either, given my limited, level 0 abilities. I share my Airport with another, even older Mac, so I am guessing that the Ventura testing regimen might have missed this problem scenario, but I see that others who are running more current systems see it too. Has anything simple been suggested lately to make this annoying message go away?

No suggestions from me-- but I have Macbook Pro running Sonoma 14.0 , and I use a Seagate external backup drive. The same message pops up several times a day (from both partitions of the drive, so actually 2 messages) , seemingly with no other related activity. Or maybe when the Time Machine finishes a backup? Yes annoying but fortunately not dangerous.

This thread is mostly dead for months, but I'm chiming in to share that I'm on a Mac Studio M1-Ultra w/ a QNAP NAS and I'm having the same annoying issue. I did also (a few months ago) have a corrupted Time Machine image... perhaps from this improper-disconnecting, I just blew it away and started over.

I was suspecting that it could have been due to my wi-fi, but I've recently switched to a hardwired GbE connection, and I just did a fresh TM backup, and after the first one completed, I got the same annoying message after waking from sleep. I'm running Ventura 13.6.4.
