= SUMMARY =

Because of physical read limitations of some CD-ROM drives, the Microsoft Music Central compact disc may deny access to some files and folders. 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 three folders, listed below, from the Music Central CD-ROM:

Folders Location On Disk ——- —————-

Mmcat1c 592-593 MB Mmcat1b 591-592 MB Mmcat1a 590-591 MB

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

Files Location On Disk —– —————-

Data.wav 581 MB Data.wav 561 MB

The Music Central 96 CD-ROM contains 593 MB of data. The final file on the CD-ROM is 1c.dib.

Testing Your CD-ROM Drive
To ensure 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). 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 one of the following files to the hard disk drive:

Files Location On Disk —– —————-

Data.wav 581 MB Data.wav 561 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 winpopd.dib file on your CD-ROM to the version of winpopd.dib file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER,

fc /b d:1c.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.
