Subject: How to write a single file to exabyte tape?

I am working on a 4D/240 running 3.3.1 soon to go to 3.3.2.

I am trying to write an exabyte tape consisting of several logical volumes.
i.e. calling several programs that write the tape using the nr(v) drivers.

What I want is:
   1/ label		first file is a label identifying the tape
   2/ directory		second file is a single unix file which describes
			all the other files on the tape.
   3.../ bru or tar files.

I can write the label correctly but when I try to dump a single file onto
the tape (using either bru, tar or dd) I get an "I/O error".

If I dump a whole directory instead of a single file every thing works.

Can any body help?

Thanks, Russell.
