Aha, OK. So I just have two more questions:

1. So is it correct to say that the check/fix boxes apply to ALL sets, not just those marked as having problems?

2. If I check all the boxes (missing, case, unneeded, name, size, date, checksums), and run a fastscan, what is an example of a problem that the fastscan will miss?
