The majority of the media in my 132T is being displayed as 'unknown media', I think this is due to the fact that I accessed this media using the ntmsmgr.msc snap in prior to installing Backup Exec. 

I have tried to resolve this problem by following steps in veritas document http://seer.support.veritas.com/docs/258269.htm but this does not solve my problem.

The manual tells me I need to perform an overwrite operation on this media to get Backup Exec to be able to recognise it but hoe can I do this as whenever I try to erase, label or inventory it I receive 'Label Library 0001 -- The job failed with the following error: Library error - incompatible storage media detected in robotic library.'

Any ideas how I can solve this ??
