How do I format/erase media in BU Exec 7.2 from Older program

[JackPollack]

I have many Travan tapes that were formatted in an older version of BU Exec (v5 or v6). We are now currently using V7.2.

When I try to BU on the tape it wont backup. It tells me that it was formatted using a different program.

Tools -> Device Operations -> Erase is grayed out

Devices -> Erase -> Quick Does work, but I get the same error when I try to BU on the tape.

How can I use these tapes?

Thanks
