Data corruption check

I was wondering what happens if a file that is regularly synched but
seldom changes gets corrupted in the copy. As it seldom (or never)
changes the mod time will always be the same. But if the content
changes (bit flip, bad HD...) will rsync get this and synch it again?
Would I need the -c (crc) flag for this to work? That of course slows
things down quite a bit. Is this the only way to ensure that the
contents are the same on both sides?
There's also the -I, --ignore-times switch. If I use this but without -c
what method is used for checking then? Or does -I imply -c?
