Follow up. I found the problem online and I am posting the solution in case it might help someone else.
When you eject a drive, the system should remove the mount point for
the drive; however, sometimes this doesn't happen. Crashes or other
improper ejecting of drives can sometimes cause the system to leave the
drive's mount point in the hidden /Volumes directory, and then when you
attach the drive again the system recognizes an existing mount point of
the same name and will append a number to the new mount point.
To clear this problem, unmount all drives and go to the hidden
/Volumes directory by entering the text "/Volumes" in the Finder's Go to
Folder option (available in the Go menu). This should open the mount
points directory, and if you see any folders, aliases, or other files in
the directory that have the same name as your external drive, then
It worked perfectly.
Thanks again for all of the help.
