Disk Not Ejected Properly -- AGAIN AGAIN AGAIN AND AGAIN...

This the restart of a 2 year old thread. Here it is 2025 and this bug is still not resolved.

Forget all the recommendations to use a different port, a different hub, a different cable, different drive(s), to clean the ports... None of them have any impact.

The core of MacOS is UNIX which is 56 years old this year. There is a limit to what can be done with patches. My MacBook Pro is less than 18 months old (M2 Max, 96GB), it has had this problem since new. I rotate between 3 Time Machine drives (Seagate and WD) plus an external Samsung SSD.

The only thing that has changed is that instead of disconnecting 1 or 2 drives, it now disconnects all 3. So I guess the Apple engineers have been working on the issue.

Perhaps the only solution is to return to Windows?

MacBook Pro 16″, macOS 15.3

If you want Apple to address the problem, then you and everyone else who is affected must contact Apple support and get a numbered support ticket. Once they eliminate all the normal simple troubleshooting stuff, then you need to have them escalate the issue & ticket up the chain to get access to the more senior techs & engineers. Unless enough people do this, then there is no way Apple will know the extent of the issue nor will Apple have any data from those affected to analyze in order to attempt to reproduce the issue under controlled conditions so that Apple can provide a patch to macOS to address the issue.

Only complaining about the problem on the forums is not going to solve anything. Why? If Apple gets no specific details (hardware & software of all devices) & log information, then there is no way Apple (or anyone else) is ever going to understand the source of the problem. Without knowing the source of the problem & without being able to reproduce the issue....there is no way to create, test, & confirm a fix.

People should also contact the manufacturers of the devices with the issue since the problem may be on their end and not on Apple's side. I know some people have resolved external storage issues through firmware updates to those external devices. Sometimes those firmware updates may not be public and you must contact the device manufacturer.

"... it's a problem particular to your setup rather than a bug"

Apple accepted it has a bug almost 2 years ago.

There are as many setup variations as you can imagine. You can read the original thread if you are interested. Everything from a single drive connected directly to the MacBook through multiple drives connected through various brands of hubs. Every suggestion has been tried by multiple users with only one seeming to work, at least occasionally: turn off the screen saver. I'm testing that one now.

Problem caused by CalDigit 4 hub. I was NOT manually removing the disks without ejecting them. 2 of the disks are always attached and never detached.

The problem was also causing data corruption on both the external disks (one of which is Time Machine) and the internal storage on the MacBook. Disconnects while copying data usually causes data corruption. The Time Machine disk became unusable and had to be reformatted before it could be used.

Moved the hard disks disks to an older Anker USB 3 (3.1 or 3.2, not sure which) and the problem went away.

There are 3 disks attached to the CalDigit hub and all 3 would automatically detach and re-attach by themselves at the same time. Sometimes overnight and other times while working on an application.

Thanks to everyone for their suggestions.

PS. Connected to the CalDigit hub was the 3 drives (2 hard disks and 1 SSD), 2 4k 60 Hz monitors, Ethernet cable connected to a WiFi 7 router on a gigabit network (that peaks at 1.3 Gbs bidirectional, Blue-ray drive, Canon scanner and Canon Printer. The 2 hard disks have been moved to the Anker hub.

I did find people reporting this problem on another forum, don't remember which one.

Was there a question in there? Any time I've had this issue - and I have eight drives permanently connected to this Mac - cleaning lint from the port resolved the issue.

The only time I ever see "disc not ejected properly" is when I don't eject the disc properly, so I'd assume it's a problem particular to your setup rather than a bug.
