Ah, the key here is that "recyclable" means a tape which has been
previously written to, is reusable, and which not among the $tapecycle
most recently-written tapes.  Surprisingly, the term does not include
tapes that are labeled but not yet used, nor (more obviously)
unlabeled tapes.  In my testing, I just 'amlabeled' a few tapes and
then ran the taperscan algorithm, and it didn't search for them.  Then
I sent the previous email.  After doing a dump to those tapes, the
algorithm correctly searched for them.  Egg on my face :)

I'm curious as to what you're seeing, Jeffrey.  Can you position your
changer at some incorrect location and then run "amtape $config taper"
and send along the results and the amtape debug log?  If anyone else
is seeing the taperscan algorithm scan when it should be searching,
please do the same.
