Is your blocksize 0?

I had to `mt -f /dev/nst0 defblksize 0` after the wait_for_drive() 
during the load.

load)
      debug "Doing mtx -f $ctl load $slot $drive"
      ${MTX} -f $ctl load $slot $drive
      rtn=$?
      wait_for_drive $device
      ${MT} -f $drive defblksize 0
      exit $rtn
      ;;
