I read in the newest edition of Mac Addict that there were "some stability" issues when they upgraded their Blue G3 CD-RW drive to a Pioneer A05 drive. I believe they mentioned that the problems were limited if sleep functions were turned off. I have a G4 Quicksilver and have been thinking about buying one of these A05 drives and wanted to know if anyone has done that yet and if so what problems they have experienced. Also, Mac Addict states that some sort of firmware update may fix the problem with the AO5... is this similar to the 103/104 firmware updates that apple offers? Any insight would be useful.
