Apple PowerBook (Duo, 2300 Series) - Manual (Page 119)

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.
Testing your hard disk requires that you start up the computer from the Disk
Tools floppy disk. To do so, you must connect your Macintosh PowerBook
Duo 2300 series computer to a minidock and an external floppy disk drive or
insert the PowerBook into a Duo Dock.
1 Start 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 Macintosh PowerBook” in Chapter 6.
If the computer doesn’t start up normally and nothing is connected, your
computer may need repair. Contact an Apple-authorized service provider, or
call the Apple Assistance Center.
(If you don’t have access to a floppy disk drive, you may need to contact an
Apple-authorized service provider or call the Apple Assistance Center to
determine the problem with your hard disk.)
2 Open the Drive Setup icon.
You may need to look in a folder called Utilities to find Drive Setup.
Note: You can get onscreen help using the Drive Setup application program
by choosing the Drive Setup Guide, available in the Guide (h) menu when
Drive Setup is the active program.
