readcd was designed to read CDs and so is much better at reading
bad sectors and doing error correction. Also, dd doesn't always
behave correctly when it reaches the end of the disk. Sometimes
it will read too little data, sometimes too much.

Here's what the Debian Reference says about readcd and dd:
