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
Works 4.0 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 Works 4.0 compact disc:
 
   Folders                          Location On Disk
   -------                          ----------------
 
   books95\mmcat\dibs5c                 605 MB
 
To test for specific drive-capacity limitations, try to access the
following files:
 
   Files                            Location On Disk
   -----                            ----------------
 
   books95\mmcat\dibs5c\strpopd.dib     605 MB
   msworks\sports.cag                   580 MB
   msworks\currency.cag                 560 MB
 
The Works 4.0 compact disc contains 605 MB of data. The final file on the
CD-ROM is books95\mmcat\dibs5c\strpopd.dib.
 
Testing Your CD-ROM Drive
-------------------------
 
To ensure the integrity of files that you have copied from your compact
disc 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 the following files to the hard disk drive:
 
   Files                          Location On Disk
   -----                          ----------------
 
   books95\mmcat\dibs5c\strpopd.dib     605 MB
   msworks\sports.cag                   580 MB
   msworks\currency.cag                 560 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 Strpopd.dib file on
your compact disc to the version of Strpopd.dib file you copied to your
hard drive, type the following at the MS-DOS command prompt and press
ENTER:
 
   fc  /b d:\books95\mmcat\dibs5c\strpopd.dib c:\strpopd.dib
 
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.
