If the drive was busy and the script tried to umount it, it failed (correct) and gave no notification (incorrect).
I have found and corrected that error and, in the case that anyone wants to use this, I am posting the corrected script. (Mailers may add unwanted line-feeds, so I have also attached a copy which would be unaffected by that.)
