Hello,
If your cartridge is in a robotic library that has a bar code reader, then the bar code label automatically becomes the media label. If you want to label the media using backup exec, then you will have to remove the physical bar code label from the media cartridge. In order to enable a bar code label for the device, refer to the following technote:
Title: How to enable a bar code label rule and configure it for the tape device

Also refer to the following pages: 206-210 in the Administrator's manual for Backup Exec version 10.0. You can download the manual at the following link:

Hope this information helps. In case of further doubts, do write back to the forum. However if we do not receive your update within two business days, this post would be marked ‘assumed answered’ and would be moved to ‘answered questions’ pool.
