- You need to use the "s" option to rdump to specify the length of
- the tape. RDUMP doesn't write until it hits the end, instead it calculates
- how much will fit and then writes that much. Too small a length will
- result in not using the whole tape, too large a length will result in
- a failure when you hit the end.

- What options are you using to the rmt server? If you use
- /nostream/nomount/nounload you shouldn't have this problem.

-
- If you use the "d" option to specify a density of 6250 this will
- "fix" the calculation of how much can be written. The default calculation
- assumes 1600 bpi.
