Ok, thats a problem.   It just seem like it won't let you
set the block size.  

You can try putting

 $mt{setblk} = "nop";

in the config file.  If you are using a blocksize that is what the drive
expects, it _might_ work out ok.

/dev/st0 = rewind-on-close.  When ever anything gets done writing to the
tape, it will rewind.  If you use this device flexbackup will overwrite its
archives and you get only one per tape.

/dev/nst0 = no rewind-on-close.  When ever anything is done writing to the
tape, it stays at its current position unless you move it around with mt.
This is what you want.
