I am convinced the DAE Quality test might not represent a drives ability to read a pressed CD with scratches, rather to read a CD-R with artificial marker damage. When testing about a year ago I found CDs with marker damage did not seem to show the strong drives out from the weak drives (when using real cds with scratches). It should be a good test for c2 pointers, but there seem to be issues (a test on a 230a only got 50% for c2, where in real life c2 pointers are in the 99.99% range).

It is not my intention to take anything away from DAE Quality as there is nothing else that can test drives independantly.

Sounds really interesting. But as bhoar already said, the whole project has to be planned very well first to get accurate and reliable results.

Some toughts:
- How the rips should be tested/verified? You probably need some reference file to do comparisons against.
- From making some DAE tests based on the EAC DAE quality project, I know that two drives of the same make and model sometimes can't generate the same results. So how to deal with wear and tear/dirt/whatever of drives - or generally speaking how to deal with conflicting results?
- what happens when the test CDs get damaged (in the mail, somebody unintentionally scratches the CDs even more while doing the tests, etc.).

I also would be interested in participating, but I don't have very much drives to test (Plextor PX-755A, Plextor PX-708A, Samsung SH-182D, Toshiba MD-1612, Toshiba SD-R5372 and some (no name/rebaged) drives in various notebooks).
