CD-ROM Drive Problems
Check the following problems to see the possible cause and solution.
!
The system does not see the CD-ROM drive.
The drive designation is wrong and should be changed. The drive
designation for the drive depends upon the storage device configuration
in the system. To find out what drive designation letter is assigned to the
drive, double click
My Computer on the Windows 98, Windows 2000, or
Windows NT 4.0 desktop. The drive designation is below the drive icon.
As an alternative, open Windows Explorer and scroll down the list of
folders until you locate the drive icon. The drive designation is beside the
icon.
!
The drive is not reading a disc.
Check that the disc is inserted in the disc tray with the printed label side
up.
Check that the disc is a data disc, not a music disc.
Try a different disc to see if the problem is limited to one disc.
!
The disc does not eject due to a power failure or software error.
Turn off the system and use the emergency eject feature. Insert the end of
a paper clip into the emergency eject hole. Press inward on the clip to
open the door.
!
The drive plays music CDs but the sound is not heard. However,
.WAV sounds can be heard when played.
Check that the cable connecting the drive to the system board is in place
and secure.
Check the Audio volume setting.

Sound is only coming from one speaker.
Balance the speaker output by adjusting the balance in the sound software
(see the Windows Multimedia online help).
