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 World Atlas for Windows, 1997 World English Edition compact disc.
 
MORE INFORMATION
================
 
To test for specific drive-capacity limitations, try to access the
following files:
 
   Files                          Location On Disc
   -----                          ----------------
 
   SYSTEM\WLD_CD.MAD              392-624 MB
   SYSTEM\WLDWHEEL.M20            336-392 MB
   SYSTEM\MSWORLD.M20             7-336 MB
 
The Encarta compact disc contains 624 MB of data (654,593,118 bytes). The
final file on the CD-ROM is \SYSTEM\WLD_CD.MAD
 
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 Disc
   -----                          ----------------
 
   SYSTEM\WLD_CD.MAD              392-624 MB
   SYSTEM\WLDWHEEL.M20            336-392 MB
   SYSTEM\MSWORLD.M20             7-336 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 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 WLD_CD.MAD file on your
CD-ROM to the version of WLD_CD.MAD file you copied to your hard drive,
type the following at the MS-DOS command prompt and press ENTER:
 
   fc  /b  d:\system\wld_cd.mad c:\wld_cd.mad
 
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.
