Method 2: Enable UDF for DVD-ROM Drives
To enable UDF for DVD-ROM drives, follow these steps:
NOTE: Because there are several versions of Microsoft Windows, the
following steps may be different on your computer. If they are, see your
product documentation to complete these steps.
- Click Start, click Run, type msconfig in the Open box, and then click OK.
- Click Advanced.
- Click to clear the Disable UDF File System
check box, and then click OK.
- Click OK. When you are prompted to restart your computer, click Yes. When your computer restarts, UDF is disabled and you should be
able to install Encarta Reference Library.

program (such as CD-RW software) may not work correctly if you enable UDF. You
may need to disable UDF again in order for the other program to work normally.
Additional Troubleshooting Procedures
Use the procedures described in this section to further
troubleshoot this issue:
Inspect the Disc
Remove the disc from the drive and inspect the disc for damage
such as warping or large scratches. If the disc is damaged, contact the
manufacturer regarding a replacement CD.
If you experience problems
with a DVD disc, ensure that you place the DVD in a DVD drive not a CD-ROM
drive.
Clean the Disc
To clean the CD-ROM or DVD-ROM, use a disc cleaning kit, or
gently wipe the silver side of the disc with a soft, lint-free cotton cloth. Do
not use a paper cloth because it can scratch the disc. Wipe the disc from the
center, outward. Do not use a circular motion as this can scratch the disc.
If this does not resolve the issue, clean the disc using a
water-dampened cloth or a commercial CD or DVD cleaning solution. Dry the disc
thoroughly before you place it in the drive.
Test the Disc in a Different Drive
If your computer has multiple CD-ROM, CD-R, CD/RW or DVD drives,
test the disc in the other drive. For DVDs, ensure the drive bears a DVD logo
on the front. If the disc works in another drive, the original drive may not be
properly reading the disc. Please seek help from your computer or disc drive
manufacturer.
If the disc is clean and it does not work in another
drive, it may be damaged and you may have to replace it. See the section
"Obtaining a Replacement Disc" below.
Clean the Drive
You can clean the disc drive using a CD-ROM or DVD drive cleaning
disc, which are available in most computer or home electronics stores. Before
you purchase a drive cleaning disc, try troubleshooting the issue using the
remaining procedures that are described in this section.
Test Disc Read with Copy or Xcopy
Copy and Xcopy are command-line utilities that will usually
uncover a disc read issue. If Copy and Xcopy complete successfully, the issue
is unlikely to be a problem reading the disc. A failure to copy can indicate
drive or system problems and illustrate the need for further
troubleshooting.
To test disc read using Copy and Xcopy, follow these
steps:
- Click Start, and then click Run.
- In the Open dialog box, type cmd, and then press
ENTER.
- At the prompt, type one of the following commands:
- To copy a folder:
copy discdrive:\foldernamedrive:\psstest /V
- To copy the entire disk:
xcopy discdrive:\*.* drive:\psstest /V /E
NOTE: discdrive is the drive letter of the
CD-ROM or DVD drive, foldername is the name of the
folder containing files you need to access on the disk, and
drive is the letter of your system hard disk
drive
- Press ENTER.
- If you receive a "Does psstest specify a file name or
directory name?" message, press F.
- If you receive an "Overwrite ... (Yes/No/All)?" message,
press A.
NOTE: If you use the
/V switch with Copy or Xcopy, the copied files are checked to make
sure that the files were copied correctly. However, the task may take longer to
complete if you use the
/V switch.
Quit Unnecessary Software
Software that is running on your computer may interfere with
reading the disc, for example, antivirus software, firewall software, or
anti-crash software. If you disable the unnecessary software, and then restart
the computer, you may be able to read from the disc.
