Step 2: Update your hard disk driver
Hard disks with old drivers might cause problems after reinstalling system
software. Your computer might not start up, or you might not see the hard disk
icons on the desktop. To avoid these problems, it’s a good idea to update your
drivers.
The disk utilities that Apple provides won’t update some disks. You can skip
step 2 if
m You don’t have an Apple hard disk. Check the instructions that came with
your computer or hard disk to see if the manufacturer includes or
recommends a disk utility, and use that utility to update the driver.
m You’ve previously used a disk utility from a manufacturer other than Apple
to format your disk or update the driver. You’ll need to use that utility again
to perform the update. Make sure to get the latest version of the utility
from the manufacturer. An old utility will not be able to update your disk
with the most current driver.
