D’oh!
In The DAM Book, Second Edition, I mention that you can use SuperDuper! as a program to do a validated transfer on Mac (in addition to Chronosync, the program I use). Some of my readers have contacted the software publisher and confirmed that it does NOT perform a validated transfer.
Sorry about the error, and thanks to readers Kevin Johnson and Tim Baker.
If you are wondering what the heck a validated transfer is, read about it at dpBestflow.org. (The movie embedded below is form the site, and shows the use of PC software SyncBack to do the process).
