Mastering Visual C++: Testing CD-ROM Drive for File Access

ID: Q151310

The information in this article applies to:

Mastering Microsoft Visual C++, versions 1.0, 1.0a

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 C++ 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 Mastering Visual C++ compact disc:


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

   msdev\redist                         634 MB

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


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

   msdev\redist\setup.tdf               634 MB
   system\msrd2x32.dll                  620 MB
   media\library\a211_017.bmp           600 MB
   media\L12\vdL12_03.avi               585 MB

The Mastering Visual C++ disc contains 634 MB of data. The final file on the CD-ROM is msdev\redist\setup.tdf.

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 files to the hard drive:


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

   msdev\redist\setup.tdf               634 MB
   system\msrd2x32.dll                  620 MB
   media\library\a211_017.bmp           600 MB
   media\L12\vdL12_03.avi               585 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 does copy, test the file's integrity by using Fc.exe with the /B (binary) switch. For example, to compare the Setup.tdf file on your CD-ROM to the version of Setup.tdf file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER:

fc /b d:\msdev\redist\setup.tdf c:\setup.tdf

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.
