Troubleshooting Symptom/Cure Tables: System Problems After Startup - 42
CD-ROM or DVD-ROM Not Showing on Desktop
CD-ROM and DVD-ROM problems are defined by the inability to see the CD or DVD on
the desktop or to open a CD or DVD that is loaded into the drive.
Possible Cause Possible Fix
Bad CD-ROM or DVD-ROM
disc.
Try using a known-good compact disc.
CD-ROM or DVD-ROM disc
didn’t load properly.
Manually eject the disc and try again. Push a paper clip
through the manual eject hole located on the right side of
the CD/DVD slot. Restart the iMac after the disc ejects.
Note: The power must be on to eject a CD or DVD disc.
Corrupted system software If the CD-ROM or DVD-ROM drive fails to mount, boot off
the system CD that came with the unit. Do you see the
CD-ROM or DVD-ROM drive on the desktop now?
Yes: Reinstall system software. (You must use the sys-
tem software CD that came with the unit to get the cor-
rect version of the Mac OS.)
No: Go to the next step.
Master/Slave switch set
incorrectly on the back of
the CD-ROM or DVD-ROM
drive.
Make certain the Master/Slave switch (located under the
CD Adapter board) on the drive is set to Slave. The Slave
position is the switch closest to the CD Adapter connector
on the back of the CD-ROM or DVD-ROM drive. The
switch is set correctly at the drive vendor, but it may
have been moved by mistake.
Loose cable. Check all cables running to and from the CD-ROM or
DVD-ROM drive at both ends and make sure they are
attached securely.
Bad CD-ROM or DVD-ROM
drive.
Replace CD-ROM or DVD-ROM drive.
Bad HD/CD/DVD data cable. Replace the HD/CD/DVD data cable.
