= SUMMARY =

Because of physical read limitations of some CD-ROM drives, you may be unable to access some files and folders on the Microsoft Bookshelf compact disc from you CD-ROM drive. This article lists those files and supplies a method to test your CD-ROM drive.

= MORE INFORMATION =

The path to the test files should include “” example:

D:.wav

The CD-ROM drive may have difficulty reading the final two folders, listed below, from the Bookshelf ’96-’97 CD-ROM:

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

The Bookshelf compact disc contains 545 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 the compact disc to your hard 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 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 wof.wav file on your compact disc to the version of wof.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.
