I really don't know how to solve this problem? Why is bacula unable to
move to the end of data?

Doing Bacula scan of blocks:
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 4. This is correct!
The above Bacula scan should have output identical to what follows.
Please double check it ...
=== Sample correct output ===
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
=== End sample correct output ===
If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.
Skipping read backwards test because BSR turned off.
=== Forward space files test ===
This test is essential to Bacula.
I'm going to write five files then test forward spacing

Ah, I see you have an autochanger configured.
To test the autochanger you must have a blank tape
that I can write on in Slot 1.
Do you wish to continue with the Autochanger test? (y/n): y
=== Autochanger test ===
3301 Issuing autochanger "loaded" command.
Slot 4 loaded. I am going to unload it.
3302 Issuing autochanger "unload 4 0" command.

3303 Autochanger "load 1 0" status is OK.
