RESOLUTION
To resolve this issue, use the following methods in the
order in that they appear in.
Examine the CD-ROM or DVD Disc
Examine the disc for visible deformation or substantial
scratches.
If you experience issues with a DVD disc, make sure that
you insert the DVD into a DVD drive instead of a CD-ROM drive.
If the
issue continues to occur, proceed to the next method.
Clean the Program CD-ROM or DVD
Clean the program CD-ROM or DVD. To do this, use a CD-ROM
cleaning kit, or gently wipe the silver side of the CD-ROM with a soft,
lint-free cotton cloth from the center of the CD-ROM outward.
Note Do not use paper cloth which can scratch the plastic and leave
streaks, and do not use a circular motion when you wipe the CD-ROM.
If the issue continues to occur, clean the CD-ROM with a damp cloth or a
commercial CD cleaning solution. Dry the CD-ROM thoroughly before you insert it
into the CD-ROM drive.
Test the CD-ROM or DVD in another Drive
Try the CD-ROM or DVD in another drive. For DVDs, make sure that
the drive has a DVD logo on the front of the drive. If the disc works in this
test, then the issue may be with the original drive not properly reading the
disc. Contact your computer or disc drive manufacturer. If your computer has
multiple CD-ROM, CD-R, CD/RW or DVD drives, test the disc in the other drive.
If after you clean the disc, the disc does not work on another
computer then it is likely that the disc is bad and must be replaced. If you
see the same issues with a replacement disc as with the original disc or if the
issue continues to occur, proceed to the next method.
Clean the Drive
If cleaning the CD-ROM or DVD does not resolve the issue, clean
the disc drive by using a CD-ROM or DVD drive cleaning disc if you have one. If
you do not have one, obtain one after all of the other steps in this article
have failed to resolve the issue. Drive cleaning discs are available in most
computer or home electronics stores.
If the issue continues to occur,
proceed to the next method.
Quit Unnecessary Software
Other applications may interfere with the reading of the disc,
for example, antivirus, firewall or anti-crash software. To quit all visible
programs:
- On the Taskbar, right-click each icon, and then click Exit, Quit, Close or Disable (if these options are available).
- Press CTRL+ALT+DEL to display the Close Program window. If
any program other than Microsoft Explorer is listed, click the program, and
then click Remove. Repeat this step until all programs except Explorer have been
removed.Note Explorer is the Windows user interface.
If the issue continues to occur, proceed to the next method.
Look for Known Issues with the Drive or Recording Software
Search the Microsoft Knowledge Base for your brand and model of
CD-ROM or DVD drive. Known issues with specific drives may be found in the
Knowledge Base.
If your computer includes CD-R or CD/RW recording
(burning) software or packet-writing software, search the Microsoft Knowledge
Base for known issues with the software. Occasionally, there are conflicts,
which depends on the version of the software or with specific drives.
The Microsoft Knowledge Base is available at the following Microsoft Web site:
Check for Drive Firmware Updates
Contact the manufacturer of your computer or disc drive to see if
software updates for your drive are available. Often these are called
"firmware" updates. Occasionally updates are issued that can resolve issues
where the drive can read most, but not all, discs.
Make Sure That You Are Using Protected Mode CD-ROM Drivers
Make sure that you are using protected mode (32-bit) drivers for
your CD-ROM drive. To do this:
- Click Start, point to Settings, and then click Control Panel.
- Double-click System.
- Click the Performance tab, and then confirm that the File System entry is 32-bit. If
the File System entry is Some drives are using MS-DOS
compatibility, you may be using real mode (16-bit) CD-ROM drivers. If
this is the case, you may be unable to read certain files on the compact disc.
Contact the manufacturer of your CD-ROM drive to obtain an updated,
protected mode driver for your CD-ROM drive. For information about how to
contact the manufacturer of your CD-ROM drive, click the appropriate article
number below to view the article in the Microsoft Knowledge Base:
65416 Hardware and software third-party
vendor contact list, A-K
60781 Hardware and
software third-party vendor contact list, L-P
60782 Hardware and
software third-party vendor contact list, Q-Z
- Click OK, and then close Control Panel.
If the issue continues to occur, proceed to the next method.
Enable and Disable UDF Support
If you are using Microsoft Windows 98 or Microsoft Windows
Millennium (Me), change the Universal Disk Format (UDF) setting. To do this,
follow these steps:
- Click Start, and then click Run.
- In the Open box, type msconfig, and
then click OK.
- Click Advanced,click Disable UDF File System, and then click OK.
- When you are prompted to restart your computer, click OK, and then click Yes.
When your computer restarts, UDF support has changed. If this
does not make a difference, change the setting back.
Note Typically, UDF should be enabled. However, some drives do not
support UDF. For these drives, UDF should remain disabled. These drives cannot
read discs that only use the UDF file system.
Note DVD-ROMs require the UDF file system, unless they are a UDF
Bridge disc (mastered for both ISO 9660 and UDF).
To disable Direct
Memory Access (DMA) for the CD-ROM or DVD drive, follow these steps:
- Click Start, point to Settings, and then click Control Panel.
- Double-click System, and then on the Device Manager tab, click View Devices By Type.
- Click the plus sign (+) next to CDROM to expand the branch.
- Click the CD-ROM or DVD drive that you want to change, and
then click Properties.
- Click the Settings tab.
- Click to clear the DMA check box, and then click Close.
- Close Control Panel , and then restart the
computer.
If the issue continues to occur, proceed to the next method.
Reduce Drive Caching
To reduce CD-ROM or DVD drive caching:
- Click Start, point to Settings, and then click Control Panel.
- Double-click System and then on the Performance tab, click File System .
- On the CD-ROM or DVD tab, move the Supplemental Cache Size slider to Small.
- In the Optimize Access Pattern For box,
click No Read-Ahead.
- Click OK, and then click Close.
- When you are prompted to restart your computer, click Yes.
If the issue continues to occur, proceed to the next method.

If the issue continues to occur, proceed to the next method.
Check for Alternate Installation Locations
If your computer contains more than one CD-ROM-compatible drive
(for example, another CD-ROM drive, or a DVD-ROM drive, or a CD-RW drive), and
if you receive either of the error messages in the "Symptoms" section, cancel Setup (using the steps shown in the "If the Error Message Is
Still on the Screen" section) and then run Setup by inserting the compact disc
into the secondary drive. In most cases, the problem does not occur when you
run Setup using the secondary drive.
Or, if your computer is
connected to a network, you may be able to share the Microsoft product's
compact disc in another computer's CD-ROM drive. If you are able to share
another computer's CD-ROM drive, insert the product's compact disc into that
drive, and from your workstation, connect to the other computer and run Setup.
For example, if the other computer's name is "server" and its CD-ROM
drive is shared as "cdrom", run Setup from your computer. To do this, click
Start, click
Run, type
\\server\cdrom\setup.exe in the
Open, and then click
OK.
