Cannot backup Crackdown

[FAGAN]

Im having problems backing up this game, when I start Backup Creator it is giving me the message "unknown partition size: used bytes = 5.32mb" - any ideas?

Possible new disc protection?

mine backed up ok using clonecd and the crackdown.iso + crackdown.dvd files, and then a back-up from my back-up using clonecd disc to disc

I had the same probs backing up the original Crackdown, apparently there's a small issue with unlocking the drive in xbox backup creator. Have a read here:
