When I go to System Preferences > Time Machine > Options,  select external drives (which Time Machine has automatically excluded), and press "Save", Time Machine gleefully adds them back for exclusion as soon as I select "Options" again.


I can remove from exclusion any drives that are internally connected, but all my USB disks cannot be removed from Time Machine's exclude list.


I've read the Pondini.org FAQ (no help) and have tried deleting and reformatting the backup drive to no avail.


Any pointers greatly appreciated.
