Tried (copied and pasted the line of text) your above suggestion - SuperDuper stopped in about the same place.
I'm wondering if he has a problem on the computer that's causing both problems.
But, I do have to tell you that I posted on our pmug group about SuperDuper and gave it a glowing review. A couple people followed up with a question comparing it to CarbonCopyCloner. Several other responses were very favorable to SuperDuper. Thought you should know about that.
