doing a image file?please help!

[jennyuwi]

hi! (sorry for my english but i am german, i will try to do my best!)

my question is:
i know how to do an image file with clonecd, but when i tried to do one with a few games for example with the game harry potter 2 i waited for two hours and it went only to 3% or so. so i cancelled it.
when i tried it with the game the lord of the rings it worked perfectly; after 10 minutes the image file was done.
can somebody help if i try it next time and it happens the same as with harry potter 2?
thanks for help!!!!
