Could this be a permission issue? I'm running as root (via sudo). The
output I'm encountering is:

$ sudo /sbin/btape -c /etc/bacula/bacula-sd.conf /dev/nst0
Password:
Sorry, try again.
Password:
Tape block granularity is 1024 bytes.
btape: butil.c:285 Using device: "/dev/nst0" for writing.
13-Aug 13:32 btape JobId 0: 3301 Issuing autochanger "loaded? drive 0"
command.
13-Aug 13:32 btape JobId 0: 3302 Autochanger "loaded? drive 0", result:
nothing loaded.
13-Aug 13:32 btape JobId 0: 3301 Issuing autochanger "loaded? drive 0"
command.
13-Aug 13:32 btape JobId 0: 3302 Autochanger "loaded? drive 0", result:
nothing loaded.
btape: btape.c:383 open device "LTO-4" (/dev/nst0): OK
