we use BE 9.1 1158.7 on NW65SP5.
The same version on my pc client.

Our hardware is:
- Autoloader with 8 tapes: Sony TSL-11000
- Streamer with 1 tape: HP Ultrium-3

If I start BE 9.1 on the client and view all medias in the menu
- Media
- All Media
in the column "Current Remaining Bytes" I see:

- a normal green or grey bar with the
remaining bytes in percent for the Sony Autoloader
=> that's ok

- "N/A" for the HP Ultrium-3.
=> here the green or grey bar is missing

Is this a bug or what can I do, that I
can see the green/grey bar for the Ultrum-3?
