Recently I made the error of changing the name of the external drive that I use to store my Lightroom Catalog and image files. Of course that resulted in a real mess and the inability of using Lightroom until it was corrected. I have Lightroom functioning again, but I need to cleanup the catalog as I now have numerous drives showing that were not there before. Most of the drives are titled something like "Macintosh SSD@snap-434034 (or a similar number) One shows as VM.
Can anyone tell me how these drives were created and how can I remove them.
