Cause 1: You don't have an Apple hard disk.
Solution 1: Use the disk utility recommended by the manufacturer of your hard disk to update the drivers on your system before installing the Mac OS. Make sure to get a version of the utility that is compatible with the software you are installing. An old utility will not be able to update your disk with the most current driver.
Cause 2: You've previously updated your Apple hard disk with a non-Apple disk utility.
Solution 2: You need to use the utility you used previously to update the driver again. To ensure a successful update, obtain the latest version of the utility from the manufacturer.
Cause 3: Your hard disks may need to be reinitialized before you can update the driver.
Solution 3: Reinitializing your hard disk will completely erase the disk. Be sure to back up all the files on the hard disk before proceeding. For instructions on reinitializing the hard disk, see the manual that came with your computer, but use the Drive Setup program provided on the Mac OS CD to perform the initialization, even if a different Apple disk formatting utility was supplied with your computer.
