Hang during Smart Update

[hoodsmom]

Along these lines - is there a way to tell whether SD! has hung when the progress bar doesn't move and the number of files read isn't being updated? Can I trust Activity Monitor to tell me if SD! has really hung?

I copy to two backup volumes, one daily and one "whenever." I was copying to the "whenever" volume when SD! seemed to hang. Unfortunately it seemed to get stuck in a folder containing many GB of info. After trying a couple of times, I deleted the folder from the target volume and tried to copy the folder using the Finder - which also hung. Finally, I copied the files a few at a time - it took a couple of restarts, but the Finder finally got over whatever was hanging it up. I never did figure out what the problem was. Then I reran SD! It didn't hang, but I was surprised that it found so much out of date (I think it recopied the folder I'd just copied manually). It would have helped to know exactly which file it and the Finder were choking on.
