= SUMMARY =

Because of physical read limitations of some CD-ROM drives, some files and folders on the Microsoft Isaac Asimov’s The Ultimate Robot compact disc may be inaccessible from your CD-ROM drive. This article lists those files and tells how to test your drive.

= MORE INFORMATION =

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

Files Location on Disc —– —————-

System Support…File Read Me 441 MB GoodiesArt Original Art legs m480x24c 421 MB AsimovAssemblyPlayer 401 MB

NOTE: The Asimov’s Ultimate Robot CD-ROM contains 441 MB of data. The final file on the CD-ROM is Scrapbook File Read Me.

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 Ultimate Robot disc into the CD-ROM drive.   Open the Ultimate Robot disc.   Open the System Support Folder.   Open the QuickTime Folder.   Open the Replacement Scrapbook File Folder.   Drag the following file to your hard drive icon. Scrapbook File Read Me   Close the Replacement Scrapbook File Folder, close the QuickTime Folder, and close the System Support Folder   Open the Goodies Folder. </li>  Open the Robotoid Art Folder. </li>  Open the R6 Original Art Folder. </li>  Drag the following file to your hard drive icon. R6 legs m480x24c </li>  Close the R6 Original Art Folder, close the Robotoid Art Folder, and close the Goodies Folder. </li>  Open the Asimov Folder. </li>  Open the Robotoid Assembly Folder. </li>  Drag the following file to your hard drive icon. MacroMind Player </li></ol>

If the following error message appears while you copy any file,

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

then your CD-ROM drive cannot read the disk at the specified location. If the file does copy, compare its size with the file on the compact disc.

Comparing File Size Information

 * 1) Locate the file on the disc.
 * 2) Click the file one time.
 * 3) On the File Menu, click Get Info.
 * 4) Note the number of Bytes Used shown on the Size line.
 * 5) Repeat the above procedure with the file that was copied to the hard disk drive.

The number of bytes used should be the same for both files. If the number of bytes is different, then the CD-ROM drive is having problems reading the compact disc.

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