Sounds like it might be some sort of tape file-mark problem...

You can check the backup logs to see if block 767 is really where you want
to be to get the start of your second archive.  I bet its not.


You can also try manually positioning things to see if you can find where
the data got to:

  mt rewind ; mt fsf 1 ; flexbackup -list
  mt rewind ; mt fsf 2 ; flexbackup -list
  mt rewind ; mt fsf 3 ; flexbackup -list
