= SUMMARY =

Because of physical read limitations of some CD-ROM drives, you may not be able to access some files and directories on the Dangerous Creatures CD- ROM. This article lists some of those files and directories and explains how to test your CD-ROM drive.

= MORE INFORMATION =

The CD-ROM drive may have difficulty reading the final three directories, listed below, from the Dangerous Creatures CD-ROM:

DIRECTORIES LOCATION ON DISC ———– —————-

-606 MB -605 MB -583 MB

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

FILES LOCATION ON DISC —– —————-

09tv.avi 581 MB 06tv.avi 562 MB 07tv.avi 541 MB 06tv.avi 519 MB 00tv.avi 500 MB

The Dangerous Creatures CD-ROM contains 606 MB of data. The final file on the CD-ROM is .dll.

Testing Your CD-ROM Drive
To ensure the integrity of your files that have been copied from your CD- ROM drive to your hard disk 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 while running a CD- ROM application with Windows.

Try to copy one of the following files to your hard disk drive. For more information about how to perform this task in Windows, see your Windows printed documentation or online Help.

FILES LOCATION ON DISC —– —————-

09tv.avi 581 MB 06tv.avi 562 MB 07tv.avi 541 MB 06tv.avi 519 MB 00tv.avi 500 MB

If the following error message appears

CDR101: Not Ready

the CD player cannot read the disk at the specified location.

If the file copies, test the file’s integrity by using FC.EXE with the /B (binary) switch. For example, to compare the Ver.dll file on your CD-ROM with the Ver.dll file on your hard disk drive, type the following at the MS- DOS command prompt and press ENTER

fc /b d:.dll c:.dll

where your CD-ROM drive is drive D, and your hard disk drive is drive C.

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