Because of physical read limitations of some CD-ROM drives, some files and folders on the Microsoft Encarta for the Macintosh, 1996 edition compact disc may be inaccessible from your CD-ROM drive. This article lists those files and tells how to test your CD-ROM drive.

The CD-ROM drive may have difficulty reading the files located on the compact disc. The files are:

Encarta Files053339a.mid 648 MB Encarta Files047518a 628 MB Encarta Files014712a 608 MB Encarta Files041772a.mov 588 MB Encarta Files040371a.mov 568 MB

NOTE: The Encarta 96 Encyclopedia compact disc contains 648 MB of data. The final file on the disc is T053339a.mid

Testing Your CD-ROM Drive
The CD-ROM drive may have difficulty reading files located on the outer portion, or track of the disc. To test for specific drive- capacity limitations, do the following:

  Insert the Encarta 96 Encyclopedia compact disc into the CD-ROM drive.   Open the Encarta 96 Encyclopedia disc.   Open the Encarta Files Folder.   Open the MIDI Folder.   Drag the following file to your hard drive icon. T053339a.mid   Close the MIDI Folder and open the Animations Folder.   Drag the following files to your hard drive icon: T047518a T014712a   Close the Animations Folder and open the Movies Folder. </li>  Drag the following files to your hard drive icon. T041772a.mov T040371a.mov </li></ol>

If the following error message appears when you copy either file, then your CD-ROM drive cannot read the disk at the specified location:

The file couldn’t be read, because a disk error occurred. Do you want to continue copying?

where is the name of the file you are trying to copy.

If the file does copy, compare its size with the file on the disc. To compare file size information, do the following:


 * 1) Locate the file on the compact disc.
 * 2) Click the file one time.
 * 3) On the File Menu, click Get Info.
 * 4) On the line displaying the Size, make note of the number of bytes used.
 * 5) Repeat the above procedure with the file that was copied to the hard disk drive.

The files should use the identical number of bytes. If the number of bytes is different, then the CD-ROM drive is having problems reading the compact disc.

For additional information, contact your CD-ROM drive manufacturer.
