Those are just hashes, and I already know that whatever internal crc the drive uses has missed a single bit error, so I'm settling for nothing less than a byte for byte comparison :)

Md5 and SHA256 won't miss single bit errors. As I remember, they're designed so that single bit or other small differences in the input yield very large differences in the hash value.
