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

The Encarta Virtual Globe 1998 compact disc contains 629 MB of data. The final file on the CD-ROM is System.spl.

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). You can use this 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:

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 drive 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 Bottom.spl file on the CD-ROM to the version of the Bottom.spl file you copied to your hard disk drive, type the following at the MS-DOS command prompt, and then press ENTER:

fc /b d:.spl c:.spl

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.
