As said by others. The native capacity is 400Gb and Bacula simply  
writes to the tape until the write does not succed which Bacula take  
as "tape full". If you have some (full) tapes with less than 400Gb you  
either have some older tapes (LTO-2) or problem with your hardware or  
tapes. The tapes with more than 400Gb simply contains data which can  
be better compressed by the built-in compression of the drive.
