Apple 6400 appendix Problems using ISO 9660 or High Sierra discs, Problems playing audio CDs

You can’t save changes you make to information on a CD-ROM disc.

mA CD-ROM disc is a read-only medium. This means that information can be read (retrieved) from it, but not written (stored) on it. You can save the changed information on a hard disk or floppy disk.

Problems using ISO 9660 or High Sierra discs

You cannot access files on a CD-ROM disc that uses the ISO 9660 or High Sierra format.

mDiscs in the ISO 9660 and High Sierra disc formats have version numbers attached to file names. Some application programs need these version numbers in order to work with files. To make the version numbers available to programs on your computer, follow these instructions.

Drag the CD-ROM disc icon to the Trash. When the tray opens, hold down the Option key and push the tray back in. Continue to hold down the Option key until the disc is in the drive. The program you are using should now be able to locate file names on that CD-ROM disc.

mMake sure that Foreign File Access, ISO 9660 File Access, and High Sierra File Access are present in the Extensions folder in your System Folder on your hard disk.

Problems playing audio CDs

You don’t hear any sound when you play an audio CD or an audio track on a CD-ROM disc using the AppleCD Audio Player.

mIf you have headphones or speakers connected to the computer, adjust the connectors to make sure they are firmly connected. Make sure the volume control on your headphones or speakers is not turned down too low.

mIf you do not have headphones or speakers connected to the computer, make sure that nothing else is plugged into the sound output port (-) on the back of your computer.

mIf you are using a CD-ROM disc over a network, you won’t be able to hear the audio portion.

mMake sure the volume is turned up in the AppleCD Audio Player. With the Audio Player open, drag the volume control slider up, use the volume controls on your computer, or press the Up Arrow key on your keyboard.
