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 Mastering
Visual Basic 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 two folders, listed
below, from the Mastering Visual Basic compact disc:

  Folders                            Location On Disk
  -------                            ----------------

  Root directory                        447-447 MB
  Master                                420-439 MB

To test for specific drive-capacity limitations, try to access the following
files:

  Files                              Location On Disk
  -----                              ----------------

  Setup.lst                             447 MB
  Master\Mvb.m14                        437 MB

The Mastering Visual Basic compact disc contains 451 MB of data. The final file
on the disc is Setup.lst.

Testing Your CD-ROM Drive
-------------------------

To ensure the integrity of files that have been 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 can occur with Windows CD-ROM applications.

Attempt to copy the following files to the hard drive.

  Files                              Location On Disk
  -----                              ----------------

  Setup.lst                             447 MB
  Master\Mvb.m14                        437 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 disc 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 setup.lst file on your CD-ROM with the setup.lst file on
your hard disk drive, type the following at the MS-DOS command prompt and press
ENTER:

  " fc /b d:\setup.lst c:\setup.lst " (without the quotation marks)

If you receive errors, the CD-ROM drive is having problems reading the disc at
that location.
