The steps in this article help you to verify that your CD-ROM drive or DVD-ROM drive can correctly read the compact disc.
Inspect and Clean the Compact Disc
To verify that the compact disc is clean and free of scratches, inspect the
shiny side of the disc. Clean the disc by wiping it with a soft cloth in a
straight line, starting from the center of the disc and wiping toward the
edge. If there are no visible scratches, and if the errors still occur
after you clean the compact disc, follow the steps in the next section. If
the compact disc appears scratched, try a new compact disc.

drive cannot read the contents of the entire compact disc.

Turn Off Enhanced BIOS Features
WARNING: Incorrectly altering hardware BIOS settings can cause serious problems that may cause your computer to fail to start or fail to function correctly. Microsoft cannot guarantee that problems that result from the
incorrect setting of hardware BIOS options can be solved. Alter the
hardware BIOS settings at your own risk.
Most computers have several enhanced settings that allow the computer to
fully use the computer hardware. These high-speed settings can cause
the system to become unstable; turning off these features may make the
computer more stable. Contact your computer manufacturer for information
about entering the basic input/output system (BIOS) and changing the BIOS
settings. You can enter the BIOS on most systems immediately after turning
on the power. Usually a keystroke (for example, pressing DELETE) is required
to enter the BIOS. The common features that can interfere with Microsoft
Office programs are the following:
Memory Shadow RAM
Video Shadow RAM
Internal Cache
External Cache
Built-in Virus Protection
Newer chip sets may have more advanced features (such as memory wait
states) that may cause errors. Most BIOS installation programs have an
option to load the BIOS default settings. This option usually turns off all
advanced features.
Check for Software Updates
Outdated and incompatible software may also cause error messages to appear.
Check with the manufacturer of the computer for various software updates,
such as BIOS updates, original equipment manufacturer (OEM) Windows
updates, and CD-ROM drive driver updates.
Check Your CD-ROM Drive for Compatibility (Windows NT and Windows 2000 Only)
For Windows 2000 and Windows NT 4.0 Workstation, make sure the CD-ROM device is listed on the operating system's corresponding Hardware Compatibility List (HCL).
