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 filenames.
Some application programs need these version numbers in order to work with files. To make the
version numbers available to applications on your computer, follow these instructions.
Drag the CD-ROM disc icon to the Trash. When the door opens, hold down the Option key and
push the door closed. Continue to hold down the Option key until you see the disc’s icon on the
desktop. The application you are using should now be able to locate filenames on that CD-ROM
disc.
m Make sure that Foreign File Access, ISO 9660 File Access, and High Sierra File Access files are
present in the Extensions folder in the System Folder on your hard disk. If these files are not
present, reinstall your CD-ROM software. The easiest way to do this is by reinstalling your system
software, following the instructions in “Installing System Software” in Chapter 13.
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, 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 computer’s sound output port (f).
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 application open, drag
the volume control slider up, use the volume controls on your computer, or press the Up Arrow key
on your keyboard.
m The CD may have been paused. Click the Play/Pause button in the AppleCD Audio Player once
or twice.
