= SUMMARY =

Because of physical read limitations of some CD-ROM drives, some files and folders on the Microsoft Bookshelf for the Macintosh, 1995 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.

= MORE INFORMATION =

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

Files Location on Disk —– —————-

Books057724a.mid 570 MB Books009891a.wav 550 MB Books006836a.mov 530 MB Books006873a.wav 510 MB Books057639a.mov 490 MB

NOTE: The Bookshelf compact disc contains 570 MB of data. The final file on the disc is T057724a.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 Bookshelf disc into the CD-ROM drive.   Open the Bookshelf disc.   Open the Books Folder.   Open the MM Folder.   Drag the following files to your hard drive icon. T057724a.mid T009891a.wav T006836a.mov T006873a.wav T057639a.mov 

If the following error message appears while you copy any of the files, then your CD-ROM drive cannot read the disc 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 copying.

Comparing File Size Information
If the file does copy, compare its size with the file on the compact 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 steps 1-4 with the file that was copied to the hard drive.

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

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