= SUMMARY =

Because of physical read limitations of some CD-ROM drives, your CD-ROM drive may deny access to some files and folders on the Microsoft Dogs 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 Dogs compact disc:

Folders Location On Disk ——- —————-

Mmcat 451-451 MB Data-441 MB

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

Files Location On Disk —– —————-

Mmcat.dib 451 MB Data32.dll 440 MB

The Dogs compact disc contains 451 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 451 MB Data32.dll 440 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 player 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 xplnpopd.dib file on your CD-ROM with the xplnpopd.dib file on your hard disk 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.
