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. -------------------- Spoon http://www.dbpoweramp.com

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). |
