= SUMMARY =

Because of physical read limitations of some CD-ROM drives, some files and folders on the Microsoft Bookshelf ’96-’97 compact disc may be inaccessible from your CD-ROM drive. This article lists those files and explains how to test your CD-ROM drive.

= MORE INFORMATION =

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

Files Location on Disc —– —————-

Installer Script 614 MB Books.idx 599 MB Books.dib 534 MB

NOTE: The Bookshelf compact disc contains 614 MB of data. The final file on the disc is Installer Script.

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, try to copy these files from the compact disc to the hard disk. If they cannot be successfully copied, your CD-ROM drive cannot read the CD at that location. If they do copy successfully, compare the file sizes of the file on the compact disc and the copied file to make sure the file was copied correctly.

Copying Files from the Bookshelf Compact Disc to the Hard Drive

 * 1) Insert the Bookshelf ’96-’97 disc into the CD-ROM drive.
 * 2) Open the Bookshelf ’96-’97 disc.
 * 3) Drag the Installer Script file to your hard drive icon.

If the file copies successfully, proceed to step 4. If you get an error message, skip to step 9.

  Open the Books Folder on the compact disc.   Open the ZIPCODE Folder.   Drag the Zip.idx file to your hard drive icon. 

If the file copies successfully, proceed to step 7. If you get an error message, skip to step 9.

  Close the ZIPCODE Folder and open the MM Folder on the compact disc.   Drag the Yircomp.dib file to your hard drive icon.   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 files do copy successfully, you should compare their sizes with the size of the corresponding file on the compact disc. For each file that you successfully copied from the compact disc to the hard disk, do the following:


 * 1) Locate the file on the compact disc. For example, locate Installer Script 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 corresponding file that you copied to the hard drive. In this example, you would repeat steps 1-4 for the Installer Script file that you had copied to the hard drive. The file sizes should be identical. 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.
