OK, in general TZ uses a simple passive copy protection system(s).
There are some steps (if you have downloaded the tzcp 1.5.x) like :
increase file size,
adding bad sectors / weak sectors
or a ghost file
So for cloneCD or other it shouldn't be any problem.
Also give it a try using blindRW or GameJack or other 1:1 copy software that are working using Raw engine.
