I looked at below post but i can't perform these steps as it will destroy the data i have on the tape im trying to catalog.

Do you know how to go about cataloging these tapes. With your instructions i was able to catalog other tapes but just not these one's.

Here is what i did.

Yealry Tape 1 was inventoried> Cataloged and restored, worked like a charm.

Yearly Tape 2 was inventoried> but cant catalog it. It give me above error.

Thanks,
