I just got a new external LaCie d2 burner and some Fujifilm DVD+R discs. Using an Apple with Toast 6 I tried backing up some data files onto a new dvd disc. The burn completed fine but when I insert the disc into the powerbook G4 drive it won't mount the disc, it'll automatically eject it. But I'm able to mount it from the external drive. I would really appreciate it if anyone can help me figure this out. thanks!
