Finder displays wrong volume names, drive status (High Sierra) My JetDrive volume is inexplicably showing as "Dropbox Installer" in the Finder. If I eject and re-mount it, the same.

If I try to browse "TB Backup" I get:



This mess is preventing my SuperDuper backups from working.
I was able to go to the apple menu, choose 'force quit' and choose finder.  The button changed to relaunch and then it picked up my volumes correctly.  

This still seems like a bug, but this will fix it without rebooting. :)
