Not sure if this will help but you might make sure that the drive order
is correct. Windows has problems with this. You can use the sjisn
command on windows and then use the inquire command on windows and make
sure the drive order is correct. If it is not strange things will
happen. And since you added a new drive this sounds like this might be
what happened.

While I didn't change any hardware, I did run into the labeling issue
just this last week. I had just updated the server (linux) and all of
my clients to the latest jumbo patch. I'd swapped all of my tapes out
from May and replaced them with the tape set for June. Neither
inventory, nor relabeling corrected the label mismatches between the
physical barcode and the internal label that Networker was reporting. I
had to do a hard reset (nsrjb -HHEv) followed by relabeling of all of my
tapes. Since this is the first time that I've had this issue, I cannot
say that this was the "right" solution. I've had different quirks with
v7.3.x and there are documented work arounds in the release notes for
some of them. I will try something different next time, putting the
tape library into service mode per the tech notes, to see if I can avoid
the hard reset.
