[QUOTE="Sherman Homan, post: 483655, member: 22094"] Under System 9 you don't need the CD extension if you boot with a Mac formatted CD in the drive. So, pop in a known good CD and restart. If it doesn't show up, your CD drive is most likely dead. Ditto for the Zip. However, if both the Zip and the CD seem dead there could be a problem with the the bus they are on. That model has two, one for the boot drive, one for the Zip/CD. Diagnosing this depends on how much time and effort you want to deal with. The problem is probably not related to non-Mac media or inappropriately removing media. That should have cleared after a restart. Good luck! [/QUOTE]
