Disk did not eject properly

This is a common problem.

Don't connect the drive to the Mac through the hub.

Yes, the drive should be connect directly to one of the Thunderbolt/USB ports on the computer.

Also, check System Settings and disable "Allow hard drives to Sleep when possible".

And while you're at it, if this is an M1/M2 Mac mini, you can safely disable Sleep for the computer. The Mx processors don't need it and it seems to cause plenty of problems for peripherals. Continue to allow the display to sleep, if you like.

My external drives keep connecting and disconnecting to my Macbook Pro. It does this automatically and unless I turn off the computer or disconnect the drives, it just keeps doing it. If I forget to turn OFF the computer, when I wake it up, I have HUNDREDS of these messages and I have to delete them one at a time. It takes about 10-15 mins to delete each.

I've tried everything to stop this but nothing works. Is there at least an easy way to delete every one of these messages without having to do each, individually?

I have just about lost all faith in Apple because of this. You'd think they could fix this in an update, but no...it just keeps doing it.

I'm about to go back to (ugh!) Windows.

It sounds like your external drive is having trouble maintaining its connection to the MBP. There are several reasons this may be happening, and it likely will not be fixed with a software update. Most likely it's a failure of the drive itself, or the drive enclosure or cable.

I suggest you please post your problem as a new question in the community so that all may see it fresh and give it the full attention that it deserves.

I have been having this problem with a 1 Tbyte Crucial X6 solid-state drive on my 2018 MacMini and contacted the supplier. At first, they said I needed to move the drive to a different port on the Mini, which stopped the disk ejection errors for about 10 days before it started again. Yesterday I complained to them again and got the following

"We would like to inform that we would request you to update the system and certain models of internal SATA drives might unexpectedly disconnect from your computer after your Mac wakes from sleep. This can occur if your Mac automatically goes to sleep or if you manually put your Mac to sleep. We would like to inform that to resolve this issue, update to macOS Ventura 13.5 or later." This seems to imply that Crucial thinks it may be an incompatibility between the MacOS and the Crucial drive.

I had already updated to Ventura 13.5, but I upgraded to 13.6.1 and will see what happens.

Try the settings shown here Wake up a remote Mac mini - Apple Community, might fix.

You're welcome. 🙂

Are these Bus Powered drives or do they have their own AC power?

Yes, Bus, both of them. I have them hooked to adapter as the Macbook Pro doesn't have enough connectors. I tried hooking one directly to the Macbook, but it still kept connecting and disconnecting.

OK, changed settings, now we'll see if that helped. Thank you so much for your time trying to help with this problem, greatly appreciated.

And the Adapter is AC powered or Bus powered?

You’re welcome 👍 🤞
