Yes. I can see them with "list volumes".

And "mtx -f /dev/changer status" says:

mtx -f /dev/changer status
  Storage Changer /dev/changer:1 Drives, 8 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 8 Loaded):VolumeTag =
KDZ003L4
      Storage Element 1:Empty
      Storage Element 2:Empty
      Storage Element 3:Empty
      Storage Element 4:Empty
      Storage Element 5:Full :VolumeTag=KDZ000L4
      Storage Element 6:Full :VolumeTag=KDZ001L4
      Storage Element 7:Full :VolumeTag=KDZ002L4
      Storage Element 8:Empty

I imported them into Bacula using "update volumes".
Also, "list volumes" lists them OK.

One problem here.. when running "readlabel", an error comes out:

Tape block granularity is 1024 bytes.
btape: butil.c:290 Using device: "/dev/nst0" for writing.
31-Jan 18:44 btape JobId 0: 3301 Issuing autochanger "loaded? drive 0" command.
31-Jan 18:44 btape JobId 0: 3302 Autochanger "loaded? drive 0", result
is Slot 8.
btape: btape.c:477 open device "Fita" (/dev/nst0): OK
*readlabel
31-Jan 18:45 btape JobId 0: Error:
btape: btape.c:526 Volume has no label.
