I'm using dd to copy data from an old hard drive to a new one. I want to be sure that the data's integrity is secure.On this answer, Gilles saysIf [dd] terminated successfully, then the backup is correct, barring a hardware faultWhat does that mean exactly? Does dd have some kind of built in verification?If I were to use rsync instead, I run a second pass with --checksum as well, to verify. Is that kind of paranoia justified?
Does dd do any kind of verification?
dd;verification;integrity
