= SUMMARY =

Because of physical read limitations of some CD-ROM drives, the Microsoft Encarta 1995 CD-ROM may deny access to some files and folders. 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 three folders, listed below, from the Encarta 1995 CD-ROM:

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

The Encarta 1995 CD-ROM contains 644 MB of data. The final file on the CD-ROM is Mmcat.dib.

Testing Your CD-ROM Drive
To ensure the integrity of files that have been 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 can occur with Windows CD-ROM applications.

Attempt to copy one of the following files from the CD-ROM to your hard disk drive. 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 disk at the specified location.

If the file copies, test the file’s integrity using Fc.exe with the /B (binary) switch. For example, to compare the ngpopd.dib file on your CD-ROM with the ngpopd.dib file on your hard disk drive, type the following at the MS-DOS command prompt and press ENTER:

fc /b d:.dib c:.dib

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