What is "non-visible" data?
Why can't FFS copy that as well?

If I get FFS to copy over my whole C: drive into a folder on an external drive
and then format and re-install windows on the C: drive, would it be safe to
say that I won't lose any data?

Hi there,

I just want to check two things...
■ If one chooses the C: drive as the master drive and the root of another
drive as the mirror then can one then boot off the mirrored drive? If not, why
not?
■ IsFreeFileSync capable of copying files that are in use by the system?
