================================================================ ==

The information in this article applies to:

 == Microsoft Encarta World Atlas for Windows, 1997 World English Edition == 

= SUMMARY =

Because of physical read limitations of some CD-ROM drives, your CD-ROM drive may deny access to some of the files and folders on the Microsoft Encarta World Atlas for Windows, 1997 World English Edition compact disc.

= MORE INFORMATION =

To test for specific drive-capacity limitations, try to access the following files:

Files Location On Disc —– —————-

SYSTEM_CD.MAD 392-624 MB SYSTEM.M20 336-392 MB SYSTEM.M20 7-336 MB

The Encarta compact disc contains 624 MB of data (654,593,118 bytes). The final file on the CD-ROM is _CD.MAD

Testing Your CD-ROM Drive
To ensure the integrity of files that you have copied from your CD-ROM drive to your hard disk drive, compare the files using the MS-DOS File Compare program (Fc.exe). This test can be used to determine if the CD-ROM subsystem is functioning properly at the device driver or hardware level(s).

The Fc.exe utility is a useful method for testing problems related to general protection (GP) faults or other critical errors (such as read errors or out of memory messages) that may occur when you use CD-ROM drives with Windows programs.

Attempt to copy one of the following files to the hard disk drive:

Files Location On Disc —– —————-

SYSTEM_CD.MAD 392-624 MB SYSTEM.M20 336-392 MB SYSTEM.M20 7-336 MB

For more information about how to perform this task in Windows, see your Windows printed documentation or online Help.

If the following error message appears:

CDR101: Not Ready

the CD-ROM player cannot read the disc at the specified location. If the file does copy, test the file’s integrity by using FC.EXE with the /B (binary) switch. For example, to compare the WLD_CD.MAD file on your CD-ROM to the version of WLD_CD.MAD file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER:

fc /b d:_cd.mad c:_cd.mad

where D is the letter of your CD-ROM drive, and C is the letter of your hard drive.

If you receive errors, the CD-ROM drive is having problems reading the disc at that location.
