How to terminate job if no writeable media present

Yes John.
I know what you are on about, but the reason why I have not used this option is because my question is only if there is no media in the tape drive for it to cancel the job rather than stopping after so many hours of writing (cancellation).

The tapes are scheduled to backup everyday Monday to Friday.

So is it possible for it not to start if it reads no media the tape drive?
