Trying to understand verify vs exact copy



Hi. I have been reading that verification of files burned does not indicate that byte for byte, the information has been copied exactly. While my software burning program (Sonic 7 non-plus version that came with my Dell) verifies, it does not allow me to control the burning speed of the project. Since I have read that I should burn slower than what is possible, I’m concerned that the files I burn may be corrupted in some way. Is there a way to find out if the files copied are copied exactly byte for byte? Thanks.
