Okay, I know that 10.3.5 does not support it natively and all, and I have installed Patch burn II so the iApps will work, and I have toast 6.0.7 which sees it fine. The System Profiler recognizes it--so any idea why if I put in a blank disc into the drive, it will not mount on the Finder desktop, but if I put in either a manufactured one or a self made one that already had data on it-it does?
