SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, your CD-ROM
drive may deny access to some of the files and folders on the Microsoft
Encarta Encyclopedia for Windows 1997 standard edition 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 Encarta Encyclopedia 1997 Standard edition:
 
   Folder                          Location On Disc
   ------                          ----------------
 
   Mmcat\Wavs                         644-646 MB
 
To test for specific drive-capacity limitations, try to access the
following files:
 
   Files                          Location On Disc
   -----                          ----------------
 
   Mmcat\Wavs\Atlas.wav               644-645 MB
   Encyc97\Mm\Avi\T041770a.avi        631-633 MB
   Encyc97\Mm\Avi\T027263a.avi        617-620 MB
   Encyc97\Mm\T047517a.wav            599-600 MB
   Encyc97\Mm\T012601a.wav            580-581 MB
 
The Encarta 1997 Standard compact disc contains 644 MB of data. The
final file on the CD-ROM is \Mmcat\Wavs\Wof.wav.
 
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 one of the following files to the hard disk drive.
 
NOTE: For more information about how to perform this task in Windows, see
your Windows printed documentation or online Help.
 
   Files                          Location On Disc
   -----                          ----------------
 
   Mmcat\Wavs\Atlas.wav               644-645 MB
   Encyc97\Mm\Avi\T041770a.avi        631-633 MB
   Encyc97\Mm\Avi\T027263a.avi        617-620 MB
   Encyc97\Mm\T047517a.wav            599-600 MB
   Encyc97\Mm\T012601a.wav            580-581 MB
 
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 Atlas.wav file on your
CD-ROM to the version of Atlas.wav file you copied to your hard drive,
type the following at the MS-DOS command prompt and press ENTER,
 
   fc  /b  d:\mmcat\wavs\atlas.wav c:\atlas.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.
