I can manipulate the changer with amtape and mtx just fine, but when I
run "amtape <config> current" it always shows the information from the
last tape that was labeled, even if I completely eject the magazine,
power everything off and put in a brand new tape when everything is back
up. I have even tested this using dd instead of amtape, so at this point
I know that it is not an AMANDA problem at all.

Any ideas on debugging the hardware/software to find out which one is
the problem. This drive/changer worked fine in another machine running
off an older Adaptec card and it is now running off an Adaptec AIC7899
that came with my Dell tape changer. Both drives are running off the
same card, different channels. Right now I am thinking that the drive is
returned cached information when you try to pull data from it and my
boss has suggested that the driver isn't sending a close() system call
to the device and that may be a reason for retrieving the wrong info.
