PSS ID Number: Q151319 Article last modified on 05-21-1996

= SUMMARY =

Because of physical read limitations of some CD-ROM drives, your CD-ROM drive may deny access to some of the files and folders on the Microsoft Works 4.0 compact disc. 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 folder, listed below, from the Works 4.0 compact disc:

Folders Location On Disk ——- —————-

books955c 605 MB

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

Files Location On Disk —– —————-

books955c.dib 605 MB msworks.cag 580 MB msworks.cag 560 MB

The Works 4.0 compact disc contains 605 MB of data. The final file on the CD-ROM is books955c.dib.

Testing Your CD-ROM Drive
To ensure the integrity of files that you have copied from your compact disc 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 the following files to the hard disk drive:

Files Location On Disk —– —————-

books955c.dib 605 MB msworks.cag 580 MB msworks.cag 560 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 drive 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 Strpopd.dib file on your compact disc to the version of Strpopd.dib file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER:

fc /b d:5c.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.
