As you are saying the tape is already written with some data, i doubt this is a problem with multiple retentions per media. Enable this property in master server properties. By default this check box will be cleared.
thanks for the quick replay
I have allready marked this check box and and the backup job is still het failed
when i reaplace media the backup is runing just fine-but i cant use this media
I tried to add the Bpcd log but i dont see related errors to this problem
bpcd log is for connectivity issues.
bptm for tape management.
Please bear the following in mind:
Media servers do not share media by default.
Multiple retentions are not allowed by default and certainly not recommended.
Media, drive and STU densities must match.
Available media must be in the robot.
Scratch pool must be marked as 'scratch' in pool properties.
If different pool is specified in policy or schedule, check pool and Scratch.

About how NB writes to tapes - I think this will help you understand why the tape is listed at FULL with only 500 gb on it.
