This isn't a Bacula option.  It's a tape drive option.

When you put the tape into the drive, the drive tries to determine 
the density already on the tape.  It likes to keep it the same as the 
exsiting tape.  What you need to do is tell the drive to do something 
else.

I've never tried it.  On the panel of your DLT drive, there should be 
a button to set the density and override the setting that it found.  
Try that.  Let us know.
