I believe at least one of the copy protection schemes used, Safedisc, writes a cryptographic signature on the CD that cannot be read or written using "normal" means. I'm not sure what "normal" means exactly, so don't ask. When the application starts up, it checks for the presense of this signature on the CD. If its not there, the application aborts. I don't think there is any easy way to copy the signature, therefore pirates hex edit the executable to remove the code that checks the CD. They then copy everything except the signature.
