= 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 619-625 MB Data-601 MB Data-583 MB

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

Files Location On Disk —– —————-

Mmcat.dib 625 MB Data.avi 601 MB Data05n2.avi 580 MB

The World of Flight CD-ROM contains 625 MB of data. The final file on the CD-ROM is Mmcat.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.dib 625 MB Data.avi 601 MB Data05n2.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:.dib c:.dib

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