Problems with clonecd

[domert]

Hi!
I am using a GCE-8240B to make backups of my PSX games with clonecd (CCD). Crash Bandicoot 3 worked fine, but Resident Evil 2 had problems. When I try to read the original disc, CCD tells me that "Failed to read sector 12,13,14,15" and then it reads until about sector 68000 where it starts getting _a lot_ of failed sectors, and the reading takes forever. What is going on? What could be wrong and how can I correct it?
