Testing your hard disk

The following steps will help you determine whether you have a problem with your hard disk or a problem with the system software on your hard disk.

1Start up the Macintosh PowerBook with the Disk Tools disk that came with your computer.

If the computer starts up normally, you may have a problem with the system software on your hard disk. If the computer starts up but you don’t see the hard disk icon, you may have a problem with the hard disk.

If the computer doesn’t start up normally, you may have a problem with equipment connected to your Macintosh PowerBook. See “Problems with Equipment Connected to Your Computer” in Chapter 7.

If nothing is connected, your computer may need repair. Contact an Apple- authorized service provider, or call the Apple Assistance Center.

2Open the Drive Setup icon.

You may need to look in a folder called Utilities to find Drive Setup.

Note: You can get on-screen help using the Drive Setup application program by choosing the Drive Setup Guide, available in the Guide (h) menu when Drive Setup is running.
