= SUMMARY =

Because of physical read limitations of some CD-ROM drives, the your CD-ROM drive may deny you access to some files and folders on the Microsoft Oceans compact disc. This article list 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 folder, listed below, from the Oceans compact disc:

Folders Location On Disk ——- —————-

mmcat4c 569 MB

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

Files Location On Disk —– —————-

mmcat4c.dib 569 MB data1.scr 551 MB

The Oceans CD-ROM contains 569 MB of data. The final file on the CD-ROM is mmcat4c.dib.

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 disk drive:

Files Location On Disk —– —————-

mmcat4c.dib 569 MB data1.scr 551 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 does copy, test the file’s integrity by using FC.EXE with the /B (binary) switch. For example, to compare the Wofpopd.dib file on your compact disc to the version of Wofpopd.dib file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER,

fc /b d:4c.dib c:.dib

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.
