Source Integrity Verification”
This option performs an additional read and checksum calculation on the source after the copy job is complete. This ensures that there were no changes to the source while copying and provides additional protection against overheating drives. It comes at the cost of re-reading the source, meaning it takes extra time to calculate the checksums again.
