questions on clonecd

[scooba]

can one of u guys tell me the answers to this......?

Clonecd will not copy a protected game if it is scratched?
If this is the case can u repair the origial game cd with that repair fluid stuff? (Ive seen this stuff in the shops)
Will Clonecd work if it is a crack version?
Ive heard that not all the patches work, so is it fair to say that to be safe always copy protected game backups with Clonecd?

An answer to these questions would be much appriciated.THANKX!!!
