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.

1. Click Start, click Run, type msconfig in the Open box, and then click OK.
2. Click Advanced.
3. Click to clear the Disable UDF File System check box, and then click OK.
4. 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.

NOTE: By default, UDF is enabled in Windows. Therefore, another 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:

1. Click Start, and then click Run.
2. In the Open dialog box, type cmd, and then press ENTER.
3. 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
     
     
4. Press ENTER.
5. If you receive a "Does psstest specify a file name or directory name?" message, press F.
6. 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.

For additional information about how to start Microsoft Windows XP without unnecessary software, click the article number below to view the article in the Microsoft Knowledge Base: After you have performed a clean boot of Windows XP, close any remaining programs by following these steps:

Some programs listed in the notification area will not have Exit listed on the shortcut menu and you may need to click Quit, Close, or Disable depending on the choices available for that program.
   
   
3. Press CTRL+ALT+DEL, and then click Task Manager.
4. In Windows Task Manager, click Applications.
5. No programs should appear under the Task list. If any programs appear, click to select the program, and then click End Task.
6. Repeat step 5 until the Task list is empty.
7. Quit Windows Task Manager.
