SUMMARY
Because of physical read limitations of some CD-ROM drives, you may be denied access to some of the files and folders on the Microsoft Encarta Virtual Globe, 1998 Trial edition 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 Encarta Virtual Globe, Trial Edition CD-ROM:
| Folder | Location On Disc |
|---|---|
| System\Media\Home | 628-629 MB |
To test for specific drive-capacity limitations, try to access the following files:
| Files | Location On Disc |
|---|---|
| System\Media\Home\Bottom.spl | 628-629 MB |
| System\Media\Avi\T174228a.avi | 606-608 MB |
| System\Media\Avi\18352.avi | 568-571 MB |
| System\Fly\Uswest.fly | 543-547 MB |
The Encarta Virtual Globe, Trial Edition compact disc contains 629 MB of data. The final file on the CD-ROM is System\Media\Home\Topb.spl.
Testing Your CD-ROM Drive
To test 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). You can use this 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\Media\Home\Bottom.spl | 628-629 MB |
| System\Media\Avi\T174228a.avi | 606-608 MB |
| System\Media\Avi\18352.avi | 568-571 MB |
| System\Fly\Uswest.fly | 543-547 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
the CD-ROM drive cannot read the compact 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 Bottom.spl file on the CD-ROM to the version of the Bottom.spl file you copied to your hard disk drive, type the following at the MS-DOS command prompt and then press ENTER:
fc /b d:\System\Media\Home\Bottom.spl c:\Bottom.spl
where D is the letter of your CD-ROM drive, and C is the letter of your hard disk drive.
If you receive errors, the CD-ROM drive is having problems reading the compact disc at that location.
