The information in this article applies to:

= SUMMARY =

Because of the physical read limitations of some CD-ROM drives, you may be unable to access some of the files and folders on the Microsoft Close Combat 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 Close Combat compact disc. The final folder is actually the root directory of the disc, located as follows:

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

The Microsoft Close Combat compact disc contains 458 MB of data. The final file on the disc is Trouble.doc.

Testing Your CD-ROM Drive
To ensure the integrity of the 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 while running a CD-ROM application with Windows.

Attempt to copy one of the following files 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 drive cannot read the compact 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 Ir41_32.dll file on your compact disc to the version of Ir41_32.dll file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER,

fc /b d:_32.dll c:_32.dll

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 compact disc at that location.
