Thanks for the followup, ctolgc. We were pretty stumped here as to how that could have happened.

I'm still not entirely sure I understand why a second copy of your Users folder, buried elsewhere, would cause Software Update to fail the way it did. I'm going to have to try to replicate the situation here to see if I can get it to occur, and to make some kind of sense. What was the name of the "buried" directory? Were there any other files on the drive when you initially cloned it?

Now that you've cloned over, take a look at the Safety Clone feature of SuperDuper! It's a pretty great way to ensure that bad things don't happen to your working system in the future.

Thanks very much once again for the follow-up, and thanks for using SuperDuper!
