I have 3 external HDs. One is used exclusively for time machine. Files from one of the others are not being backed up. That drive is not excluded. How can I get time machine to back up that HD?
What Format is that drive? MacOS Extended?
Info window says Format: Mac OS Extended (Journaled)
Hmmm can you try excluding it, turn off TM, turn on TM, & remove the exclusion?
