hmm. I haven't noticed that behavior. Is there some trick to making it work?

just havereader=1 in changer.conf

I have that set.

I've had no particular problem, but Amanda does seem to cycle through on my
system. It does keep the barcodes listed in changer-barcodes. Maybe my
library doesn't have that quick access feature? On the other hand, I always
keep the tapes in order, so the issue rarely comes up.

That's probably why you're not seeing it -- it's hard to distinguish
between loading the "next" tape, and loading the tape with the next
desired label.

If you look at your changer debug file, you can verify that the loads
are by barcode.
