According to Apple Support, those PowerBook and iBook slot-loading drives ONLY take the standard sized CDs. Putting in an odd shaped CD-R may result in a very stuck CD. They do sell adapters that convert those small round CD-Rs into regular size CDs, and they do work, but to be honest I've only had the courage to try it once or twice on my old superdrive upgraded TiBook. OS X has no trouble figuring out what to do with the smaller discs. However, adapters are always risky especially if the small CD is not seated in ther adapter just right. USE THEM at YOUR ON RISK <--- haha... Lawyer-repellant clause. - J > My Question: > Could I use CD 200 MB (8 cm) in PowerBook G4 667 with CD-RW/DVD ? > Dominik
