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
   -----                         ----------------
 
   Books\MM\T057724a.mid              570 MB
   Books\MM\T009891a.wav              550 MB
   Books\MM\T006836a.mov              530 MB
   Books\MM\T006873a.wav              510 MB
   Books\MM\T057639a.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:
 
1. Insert the Bookshelf disc into the CD-ROM drive.
 
2. Open the Bookshelf disc.
 
3. Open the Books Folder.
 
4. Open the MM Folder.
 
5. 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 <file name> couldn't be read, because a disk error occurred.
   Do you  want to continue copying?
 
Where <file name> 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.
