Stuck Volume Mount

Earlier today I had my external SSD disconnect for some strange reason. After rebooting it appears that the OS is using the original mount name and causing the SSD to mount to a new mount name. The result of this is that I see in /Volumes the following directories:

drwxrwxr-x@ 9 XXXXX staff 288 Dec 2 21:18 MacM1Data 1

d--x--x--x 3 root wheel 96 Jan 30 11:33 MacM1Data

Where "MacM1Data" is the original mount point and "MacM1Data 1" is the new mount point. I have tried removing the "MacM1Data" directory so that I can get the SSD to mount to that location again but I get a "Operation not permitted" error. How do I fix this so that the SSD will again mount to its original location?

I ran FirstAid and it did not find any errors. I also tried to unmount the phantom mount and that did not work.

After looking through some other posts of issues I pieced together a solution to removing the phantom mount. As I stated in my original post, I was unable to remove the phantom mount from the command line. Even trying to do so using sudo would result in an "operation not permitted" error. Using Finder I was able to move the phantom mount to the trash can and then delete it. After that I was able to remount the external SSD using the original mount point. Things seem to be back to normal for now.

One symptom of a failing/corrupt drive is it will un-mount itself.

Try a different cable, a different port, or a different drive... to compare

From the terminal. umount – unmount filesystems

umount <drag&drop your external to complete the path>

You can run DiskUtility>FirstAid for directory structure repair, if errors are discovered and fixed, run it again until no errors are reported.

What does it show for the name of the external drive on the Desktop...(?)

you can change the name there like any file/folder/drive
