Hi, virtudesign.

The problem here is a bug in Jaguar: when we ask an unnamed MS-DOS volume for its name, the system crashes the call.

Try detaching any MS-DOS formatted drives -- typically, it's a flash drive that's causing the problem -- and try running SuperDuper! again. I think you'll find that'll resolve the issue.

(Note that Apple fixed this problem in Panther.)

Hope that helps.
