Is it possible to restore data from tapes without fragement 1

We are running Netbackup 7.6.1.2 on windows 2008 server.

There's a windows-nt backup, the data is backup to three tapes. No stream.

Now we found the first tape is expired and re-used, try to import the tape catalog, but it seems the fragement 1 is already gone.

Is it possible to restore the data on the rest two tapes back without the first one?

Thanks.
