Apple 6400 appendix 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 the Foreign File Access and Audio CD Access CD-ROM extensions are installed and turned on. You can find them in your 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.) 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 the drive.

mThe 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.

mMake sure the disc is 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.

mThe 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.

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 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.

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.
