Data integrity question- how much verification by SuperDuper?

Thanks. I understand your position, but very strongly disagree with your opinion and logic here.

Obviously, you rely and trust your verification tools and consider them very valuable to you. So, it makes little sense for you to turn around and say they would have little or no value to anyone else.

Do you think you are the only person concerned with matters of data integrity?

How do you think other people would want to trust your software, if you don't even want to make available tests to verify the integrity of its copying?

Of course.

In part, my questions are related to resolving differences in results of using various other tools, both to perform copying tasks and verification tasks.
