You can’t save changes you make to information on a CD-ROM disc.
m A 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.
m Discs 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.
m Make 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.
m If 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.
m If 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.
m If you are using a CD-ROM disc over a network, you won’t be able to hear
the audio portion.
m Make 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.
