The read heads for CD's and DVD's are different, it's entirely possible for one to be dirty and another work. It's also possible for the DVD part to die while the CD part still works; the original LG combo drives that came in Pismos were notorious for that. Some batches of disks are just bad, too. I've had to return packages to the store when I got several failures in a row, especially if it's been tried on different computers. Recordable media is a cheap commodity now, and QC has slipped; you cannot pay for a lot of QC when you can't sell the disks for more than a $1 or 50 cents each. Back in the day when CDR's were $10 each; they were tested more rigorously; nowadays you're probably lucky for 5 tested disks per lot, which could be thousands of disks. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
