Your computer displays the message “This is not a Macintosh disk: Do you want to
initialize it?” when you insert a CD-ROM disc in the CD-ROM drive.
m Make sure that the Foreign File Access and Audio CD Access CD-ROM
extensions are installed and turned on. You can find them in the
Extensions folder in the System Folder on your hard disk. If they are not
turned on, use the Extensions Manager control panel in the Control Panels
folder in the Apple (K) menu to turn them on. Click to put checkmarks
beside them to turn them on; then restart your computer.
m Make sure the CD-ROM software is installed. (The CD-ROM software is
already installed on Macintosh computers that come with CD-ROM drives.)
If you installed a CD-ROM drive after buying your computer, see the
manual that came with the drive.
m The disc may use a format that the Macintosh cannot recognize. Ask the
disc’s manufacturer for a disc that a Macintosh can recognize.
Your computer ejects a CD-ROM disc without giving you any error message.
m Make sure the disc is lying flat in the tray and the disc label is facing up.
IMPORTANT
If you’re using a small (8 cm) disc, make sure it’s centered within
the tray’s inner ring and the computer is absolutely level. An improperly
seated small disc in your computer may result in damage to the disc, the
CD-ROM drive, or both.
m The disc may need to be cleaned. (See “Handling CD-ROM Discs” in the
section “Handling Your Computer Equipment” in Appendix A.) If there are
visible scratches on the shiny side of the disc, you may be able to remove
them with a CD-ROM disc polishing kit (available from your audio CD
dealer). If the scratches can’t be removed, you need to replace the disc.
m The disc may be damaged. Try another disc in the drive, and try the
original disc in another drive. If the original drive reads other discs or if
the original disc also doesn’t work in another drive, the disc is probably
damaged. You need to replace it.
You can’t open a document on a CD-ROM disc.
m Try opening the application program first; then open the document.
m Read the manual that came with your CD-ROM disc. Some discs come with
software that you need to install before using the disc.
