SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, some CD-ROM
drives may deny access to files and folders on the Microsoft World of
Flight compact disc. This article lists some of 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 World of Flight compact disc:
 
Folders                            Location On Disk
-------                            ----------------
 
Mmcat\Dibs1                           619-625 MB
Data\Guides\Samm                      597-601 MB
Data\Guides\Henr                      578-583 MB
 
To test for specific drive-capacity limitations, try to access the
following files:
 
Files                                 Location On Disk
-----                                 ----------------
 
Mmcat\Dibs1\Wrldpopd.dib               625 MB
Data\Guides\Samm\sammtoon.avi          601 MB
Data\Guides\Henry\Henr05n2.avi         580 MB
 
The World of Flight CD-ROM contains 625 MB of data. The final file
on the CD-ROM is Mmcat\Dibs1\Wrldpopd.dib.
 
Testing Your CD-ROM Drive
-------------------------
 
To ensure the integrity of files that you have copied from your CD-ROM
drive 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 can occur with Windows
CD-ROM applications.
 
Attempt to copy one of the following files from the CD-ROM to your
hard disk drive.
 
Files                               Location On Disk
-----                               ----------------
 
Mmcat\Dibs1\Wrldpopd.dib               625 MB
Data\Guides\Samm\sammtoon.avi          601 MB
Data\Guides\Henry\Henr05n2.avi         580 MB
 
NOTE: 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 copies, test the file's integrity using Fc.exe with the
/B(binary) switch. For example, to compare the wrldpopd.dib file on
your compact disc with the wrldpopd.dib file on your hard drive, type
the following at the MS-DOS command prompt and press ENTER:
 
   fc  /b  d:\mmcat\dibs1\wrldpopd.dib  c:\wrldpopd.dib
 
If you receive errors, the CD-ROM drive is having problems reading
the CD at that location.
