The information in this article applies to:

 == Microsoft Bookshelf ’95 for Windows 95 == 

= SUMMARY =

Because of physical read limitations of some CD-ROM drives, you may be denied access to some of the files and folders on the Microsoft Bookshelf compact. 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 Bookshelf compact disc:

Folder Location on Disc —— —————-

Mmcat 541-543 MB

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

Files Location On Disc —– —————-

Mmcat.wav 542-543 MB Books.idx 478-538 MB

The Bookshelf ’95 for Windows 95 compact disc contains 543 MB of data. The final file on the disc is Mmcat.dib

Testing Your CD-ROM Drive
To check the integrity of files that you copied from your compact disc to your hard disk drive, compare the files using the MS-DOS File Compare program (Fc.exe). You can use this test 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:

Files Location On Disc —– —————-

Mmcat.wav 542-543 MB Books.idx 478-538 MB

NOTE: 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 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 Land.wav file on your compact disc to the version of Land.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 compact disc at that location.
