Apple 120 Series user manual You can’t open a document on a CD-ROM disc

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.

mMake sure that Foreign File Access and Audio CD Access CD-ROM extensions are installed in your Extensions Folder and are turned on. (If they are not turned on, use the Extensions Manager control panel to turn them on and then restart your computer.)

mMake 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 your drive.

mThe disc may use a format that the Macintosh cannot recognize.

Your computer ejects a CD-ROM disc without giving you any error message.

mMake sure the disc is flat in the tray and the disc label is facing up. If you’re using a small (8 cm) disc, make sure it’s centered within the tray’s inner ring.

mThe disc may need to be cleaned. (See “Handling CD-ROM Discs” 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 polishing kit (available from your audio CD dealer). If the scratches can’t be removed, you’ll need to replace the disc.

mThe 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 doesn’t work in another drive, the disc is probably damaged. You’ll need to replace the disc.

You can’t open a document on a CD-ROM disc.

mTry opening the application program first; then open the document.

mRead the manual that came with your CD-ROM disc. Some discs come with software that you need to install on your computer before using the disc.

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

mCD-ROM 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.
