Star Wars:Jedi Knight II - What copy protection is being used?

[venomhed]

I purchased Jedi Knight 2 and want to copy it. I have a Lite-On 24102b that seems to get through everything (MOH and STBC recently)

I tried the same settings I used on the above games on jedi Knight. I still get a CRC error at about 60-70% (can't remember exactly)

Anyone know what copy protection is being used? And also if known what are the Clone CD settings to copy this to an image?
Thanks!
