    Sounds like the tape header is invalid, and it will not be possible to restore from these tapes. That is taking it for granted that the old tapes were backed up to using this same drive. If you don't need the data, as a test do a Quick Erase on one of these tapes and then run a test backup to it and see if it can read the tape ok. It is a good idea to run a test restore from a new backup.
