You're unable to copy the CDs to your HDD and make ISOs or .ZIP/.7Z/etc out of them?
Are these files locked by other processes? If so, you can use Unlocker and the Assistant it comes with to close the open handles.

what condition are the discs in? Are they flawless or have visible scratches? If the latter try copying from it after wiping the disc with a lint free cloth and rain-x.
