"Elegant" Solution???

[AVI]

Hi - I have a simialr query I think;
I've just purchased SuperDuper!, I was hoping to use it to back up an external FireWire drive (1) of mine to another external drive (2).

I currently use (2) as a TimeMachine backup / general backup drive, and store most of my working documents etc. on the FireWire (1) drive rather than the internal drive, so obviously it would be convienient to be able to backup (1) to (2) [TimeMachine doesn't have a facility for this].
I assumed formt he website that SD! would allow me to do so, but FireWire (1) doesn't appear in the "from" list.
Should this work? and if so, what should I do / activate / etc ?

with thanks in advance,
