CFS2 backup problems

I have tried to make a backup copy of combat flight sim 2 an experienced some problems. Disk1 is O.K but disk 2 is giving me headace. Has anyone managed to make a backup, and if so, can you please give me some help?

i am having the exact same problem can copy cd 1 but not cd 2, i am using clone cd.
Its very strange because i got a loan an original copy of the game and copied it for myself no problem, but now im trying to copy my copy for a friend and it doesnt work.
Are you trying to copy an original cd or a backup?
