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

The information in this article applies to:

 == Microsoft Encarta Encyclopedia for Windows 1997, standard 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 Encyclopedia for Windows 1997 standard 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 the Encarta Encyclopedia 1997 Standard edition:

Folder Location On Disc —— —————-

Mmcat-646 MB

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

Files Location On Disc —– —————-

Mmcat.wav 644-645 MB Encyc97041770a.avi 631-633 MB Encyc97027263a.avi 617-620 MB Encyc97047517a.wav 599-600 MB Encyc97012601a.wav 580-581 MB

The Encarta 1997 Standard compact disc contains 644 MB of data. The final file on the CD-ROM is .wav.

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.

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

Files Location On Disc —– —————-

Mmcat.wav 644-645 MB Encyc97041770a.avi 631-633 MB Encyc97027263a.avi 617-620 MB Encyc97047517a.wav 599-600 MB Encyc97012601a.wav 580-581 MB

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 Atlas.wav file on your CD-ROM to the version of Atlas.wav file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER,

fc /b d:.wav c:.wav

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.
