Because the tape in the drive was from the wrong pool. Fair enough.

This is exactly the problem I had with an HP SureStore 718. I had to mount
each tape manually to get Bacula to use the correct set of tapes (like you,
I rotate tape sets).
However, I now have it working perfectly. See my reply to "Autoloader not
Autoloading" on 2007-08-28:

Basically, the director uses one of its own data structures when it is
deciding which tape to tell the SD to use. It queries the database to
select the tape, using the SQL:
SELECT <list of columns> FROM Media WHERE PoolID=<something> etc.
If the device is marked as an autochanger in the *bacula-dir.conf* (not just
in the SD's config file), then the director adds the following SQL into the
query:
AND InChanger=1 AND StorageId=<something>
which makes the query ignore tapes which are not in the changer.
So the bottom line is, add this line:
Autochanger = yes
to bacula-dir.conf, in this section:
Storage {
Name = Auto
