To backup Securom games I just use CloneCD using the 'Protected PC Game' setting! The backup will always install but you will need a NoCD crack to play!
But I find this is a very easy way to do Securom Backups and I havent had one not work! I do them at max speed as well! Not exactly a 1:1 but always works!

And I just checked GCW and the NoCD's are available for CS CZ so this is a no fuss way!
Since most of us use NoCD cracks anyway it foolproof! You only need the disc to install so what else do you need!

And BTW SecuROM 5.00.03.0005 found on CD1, no protection on CD2!
