I have a G4 Power Mac and just upgraded to Tiger OSX vs.10.4 about 2 weeks ago. I just tried to burn a file for someone off of a floppy disk, and my cd drive will not read the blank cd. I tried to load other cds that already had data/music on them, and those were fine. It's just the blank cds. I tried a few different cds just to make sure that it wasn't the cd. Any other thoughts?
