unable to copy files from cd


since I upgraded to Tiger the computer wont copy files from a cd to my Hd. When I try to copy them I get an stop symbol. I have enough harddisk space left so it has nothing to do with that. Very strange is that Itunes does import and copy music files to its library from the cd. I have not been able to find any help on the internet or on this forum. I hope someone can help me.
I found out that it is one cd that causes the trouble. When I insert it and try to copy files from it, it wont let me. And from then on every other cd and disk image has the same problem.
