Errors when trying to make image files

[l Joker l]

I've been trying to make some image files of some of my CD's. I've used a few different programs to try to do this, but I either get errors when I try, or it just doesn't do it at all. So far, I've used Alchol 120, Clone CD and Prassi PrimoCD Plus. I've come to the conclusion that it's not software, but a hardware issue. I have a Acer 20x10x40 CD-RW and Acer 56x CD-ROM. Both drives give out the same messages. Any help I could get would be greatly appreciated.

~Thanks in advance.
