Before you start forcibly changing bacula's notion of what tapes are 
full and what tapes are empty, you might want to try to figure out WHY 
bacula thinks your "empty" tapes are full.  I'm certainly no expert, but 
my guess would be that this is a symptom of a larger problem.  I noticed 
all your non-empty empty tapes aren't JUST marked as full, Bacula thinks 
they all have around 60MB worth of data on them, and they were all 
written to (again as far as bacula is concerned) within the space of 
about an hour.  Are your tapes in a changer?  Is it possible they were 
used without your knowledge?  I have no idea what's going on -- my point 
is only that telling bacula to treat the tapes as empty is probably more 
of a workaround than an actual solution for whatever caused them to be 
marked as full in the first place.   Personally, I would try running 
query #13 or 14 to see what jobs (if any) bacula thinks is on those tapes.


Anyway, to answer your question more directly, you can try pruning the 
offending volumes (use the "prune" command in the bacula console).  If 
that doesn't work, try purging them (again, the obvious: use the "purge" 
command), and if THAT fails, use the "update" command to directly change 
the tapes' status.
