The information in this article applies to:
 
 - Microsoft Encarta World Atlas for Windows, 1996 edition 
-------------------------------------------------------------------------------
 
SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, the Microsoft
Encarta World Atlas CD-ROM 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 folder, listed below,
from the Encarta World Atlas CD-ROM:
 
+-------------------------------+
| Folder     | Location On Disk | 
+-------------------------------+
| System\Avi | 572-640 MB       | 
+-------------------------------+
 
To test for specific drive-capacity limitations, try to access the following
files:
 
+-------------------------------------------+
| Files                  | Location On Disk | 
+-------------------------------------------+
| System\Avi\a542499.avi | 640 MB           | 
+-------------------------------------------+
| System\Avi\a174239.avi | 620 MB           | 
+-------------------------------------------+
| System\Avi\a174230.avi | 600 MB           | 
+-------------------------------------------+
| System\Avi\a174221.avi | 580 MB           | 
+-------------------------------------------+
 
The Encarta World Atlas compact disc contains 640 MB of data. The final file on
the CD-ROM is \System\Avi\a542499.avi
 
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:
 
+-------------------------------------------+
| Files                  | Location On Disk | 
+-------------------------------------------+
| System\Avi\a542499.avi | 640 MB           | 
+-------------------------------------------+
| System\Avi\a174239.avi | 620 MB           | 
+-------------------------------------------+
| System\Avi\a174230.avi | 600 MB           | 
+-------------------------------------------+
| System\Avi\a174221.avi | 580 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 a542499.avi file on your CD-ROM to the
version of a542499.avi file you copied to your hard drive, type the following at
the MS-DOS command prompt and press ENTER,
 
   fc /b d:\system\avi\a542499.avi c:\a542499.avi
 
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.
