booted from external, can't clone to another external
 

I'm booted from an external firewire drive through the FW800 port, and want to clone that drive to another external drive connected to the FW400 port. When I open SD and select each of the drives, the "using" line remains grayed out.

I can't use the internal drive at the moment, because of mandatory FileVault/Leopard/other security upgrades at my organization.

I want to smart update the FW400-connected disk. Please advise.

10.4.11, Powerbook 17", 1Ghz, registered copy of SD 2.6.2 (v87)

Have you tried restarting your Mac?

yes, set startup disk in system pref, and restarted. The menu for what SD will do is still grayed out.

OK. Quit SD! and remove the "Saved Settings" folder in Library/Application Support/SuperDuper! (off your Home folder), then try again.

ok, that worked. now I have a selectable pull-down menu.
here goes..
thanks,
