I have a handful of Mirrors set up with the verify option ON from Internal to External drive. I also have versioning OFF and deletions PERMANENT.

My PC restarted in the middle of a Sync FFS now thinks everything has been Mirrored and everything fine but I know it did not finish. Is there a way to get FFS to essentially rescan the entire source drive and make certain the destination drive is correct?

Over the years I've noticed the free space is not identical from source and destination drives. Is there any way to verify the drives short of simply deleting the destination and starting over?

"File content" comparison will do that: https://freefilesync.org/manual.php?topic=comparison-settings

PS: Unless you've pulled the power plug, it's unlikely there is any data corruption, and the sync most likely did finish just in time.
