SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, the
Microsoft Explorapedia World of Nature 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 Explorapedia World of Nature compact disc:
 
Folders                          Location On Disk
-------                          ----------------
\svga                            638
\s3-928                          637
\s3-924                          636
 
To test for specific drive-capacity limitations, try to access the
following files:
 
Files                          Location On Disk
-----                          ----------------
 
\svga\win.cnf                  638 MB
\nature\media\T182877a.avi     620 MB
\nature\media\T113428a.avi     599 MB
\nature\media\T105143a.avi     580 MB
\nature\media\T100624a.avi     560 MB
 
The Explorapedia World of Nature compact disc contains 638 MB of data. The
final file on the CD-ROM is \svga\win.cnf.
 
Testing Your CD-ROM Drive
-------------------------
 
To ensure the integrity of files that you have copied from your
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 the following file to the hard drive:
 
Files                          Location On Disk
-----                          ----------------
 
\svga\win.cnf                  638 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 drive 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 Win.cnf file on your compact
disc to the version of Win.cnf file you copied to your hard drive, type the
following at the MS-DOS command prompt and then press ENTER,
 
   fc  /b  d:\nature\winsys\drivers\svga\win.cnf c:\win.cnf
 
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.
