Ideal Super Duper Setup?

[ShosMeister]

The introduction does not give any instructions (nor searching through the entire guide) on how to do this. Being fairly intelligent with computers etc., I thought I knew how to do this. There seems to be an issue though.

I have two physical external drives. Each is partitioned to 5 partitions (Monday_BU, Tuesday_BU, etc). When I created the initial schedule, all seemed to work well. The next week though, when I changed the physical drive out, all of the backups failed indicating it could not find the backup volume.

Is SuperDuper using the name of the volume or some internal ID? If it's the name, why would it fail like this? Do I need to setup two separate schedules; one for each physical drive to run every other week?

Thanks!!!
