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

The information in this article applies to:

 == Microsoft Encarta 98 Encyclopedia for Windows == 

= 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 disc 2 of the Microsoft Encarta Encyclopedia Deluxe edition compact disc. This article lists those files and supplies a method to test your CD-ROM drive.

= MORE INFORMATION =

The CD-ROM drive may have difficulty reading the final folder, listed below, from disc 2:

Folder Location On Disc —— —————-

Encyc98666000a.qtm 649 MB

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

Files Location On Disc —– —————-

Encyc98666000a.qtm 649 MB Encyc982.m20 635 MB Encyc98.m20 626 MB Encyc98.m20 479 MB

Disc 2 of the Encarta 1998 Deluxe edition contains 649 MB of data. The final file on the CD-ROM is Encyc98666000a.qtm.

Testing Your CD-ROM Drive
To test 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 —– —————-

Encyc98666000a.qtm 649 MB Encyc982.m20 635 MB Encyc98.m20 626 MB Encyc98.m20 479 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 T666000a.qtm file on your CD-ROM to the version of the T666000a.qtm file you copied to your hard drive, type the following at the MS-DOS command prompt, and then press ENTER

fc /b d:666000a.qtm c:666000a.qtm

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

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