I’m trying to see if anyone has a resolution for this issue. I have a 2.0 dual G5 (7,2) running 10.5.8. I have an issue with the Sony Superdrive. The drive will read and burn dvds just fine, but it will whirr audibly, fail to recognize and then eject any CDs I try (burned or retail). I’ve run ASD 2.5.7 and it passed all tests. I’ve tried swapping a pioneer Superdrive from another g5 but it behaves in the same way, so I assume this is some sort of software issue. Any ideas? Any help is much appreciated!
