PGP Disk corruption

I have two PGP disks - Disk 1 and Disk 2

Mount at F and G

Today when I click Disk 1, it mounts Disk 2 and when I mount Disk 2 it also mounts Disk 2

I've unmounted, remounted, rebooted, selected auto-mount and everything I can think of

It would appear as though Disk 1 is corrupt - is there a tool to repair it?

PGP Version is 10.2.1 (Build 4461) PGP SDK 4.2.1
