Just want to say thanks
 

Just a few weeks after buying SuperDuper I experienced my first disk crash in years. Ironically my iMac's disk died in the middle of an SD backup! Fortunately I'm pretty good about backing up regularly, so I didn't lose anything noteworthy. That the crash happened during a backup wasn't completely harmless; I had to rebuild my dock and one application I had installed was no longer there, but all was easily repaired. The bottom line is that SD saved my bacon. I was within my warranty so my iMac got a new HDD from Apple, and thanks to SD I had a completely restored system 90 minutes later.

Wow, that was both terribly unlucky and terribly lucky at the same time!
