"Disk not ejected properly" in clamshell mode

[badlydrawnboy]

I have a dual workstation setup where I occasionally use my M1 Max MacBook Pro in clamshell mode with an ASD. I have a 4 TB SSD plugged into the ASD to minimize the number of cables I have to connect to my MBP when I bring it back to my desk.

The issue is that I'm getting the "disk not ejected properly" message every time I disconnect my MacBook Pro from the ASD—or at least every time I forget to eject the external SSD, which is most of the time!

Is there any workaround for this?

Did you eject the disk via software?

What software?

What software?

When you want to disconnect any external drive, you have to right click the drive icon and select "Eject disk". Otherwise you are damaging the data.

I get that. What I'm asking is if there's a workaround here. That disk contains my photos and it was always connected to my iMac Pro. I rarely had to eject it. Now, I am using a MacBook Pro as my single computer. I go back and forth between using it at my "desktop" workstation (attached to a dock and Apple Studio Display), and as a laptop.

The photos drive is attached to the Apple Studio Display. So, the issue occurs when I unplug my MBP from the dock and ASD to use it away from my desk. I try to remember to eject the photos disk first, but I often forget.

I thought I remembered an app that will automatically eject an external disk on sleep and remount it when reconnected. That might solve my problem. I searched around and found what I was thinking of—it's called Mountain.

Unfortunately, it looks like it's no longer supported.

I found the other app I was thinking about: Jettison. This should solve my problem.
