SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, the Microsoft
Bookshelf compact disc 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 Bookshelf 95 CD-ROM:
 
   Folders                          Location On Disk
   -------                          ----------------
 
   mmcat\dibs2                            541 MB
   mmcat\dibs1                            539 MB
   books\zipcode                          477 MB
 
To test for specific drive-capacity limitations, try to access the
following file:
 
   Files                            Location On Disk
   -----                          ----------------
 
   mmcat\dibs2\landpopd.dib             543 MB
 
The Bookshelf compact disc contains 543 MB of data. The final file
on the CD-ROM is \mmcat\dibs2\landpopd.dib.
 
Testing Your CD-ROM Drive
-------------------------
 
To ensure 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). 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 the following file to the hard disk drive:
 
   Files                          Location On Disk
   -----                          ----------------
 
   mmcat\dibs2\landpopd.dib             543 MB
 
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 does copy, test the file's integrity by using FC.EXE with the /B
(binary) switch. For example, to compare the Landpopd.dib file on your
 
compact disc to the version of Landpopd.dib file you copied to your hard
drive, type the following at the MS-DOS command prompt and press ENTER,
 
   fc  /b  d:\mmcat\dibs2\landpopd.dib c:\landpopd.dib
 
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.
