Drag the following files to your hard drive icon. T047517a T045001a </li></ol>

If the following error message appears while you copy either file, 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.

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 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.

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

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