Try these suggestions first

If you can’t start up from a hard disk or you don’t see the hard disk icon on the
desktop, try the following:

m If the hard disk is internal, shut down or turn off your Macintosh, wait at

least 10 seconds, and then turn it on again.

m If the hard disk is external, make sure that it is turned on and that its cable

is connected firmly; then restart the Macintosh.

m If the hard disk is your startup disk, start up with a different startup disk.

If the hard disk’s icon appears on your desktop, reinstall system software
on the hard disk (see “Installing or Reinstalling System Software” later
in this chapter).

m Check the ID numbers of all SCSI equipment connected to your computer.

Each device must have a unique ID number (If your computer came with
the optional CD-ROM drive installed, it has ID number 3.) Also check that
the chain of devices is terminated properly. For information on setting
SCSI ID numbers and terminating a SCSI chain, see the manuals that
came with your SCSI equipment.

m If none of these steps solves the problem verify and test the disk by

following the instructions in the next section, “How to Verify and Test a
Disk.”

How to verify and test a disk

The Drive Setup and Disk First Aid applications are used to verify and test
disks. They can be found on the CD-ROM disc that contains system software.
If your computer did not come with a CD-ROM drive, these applications are
on the Disk Tools floppy disk that came with your computer.

To verify and test the disk, follow these steps:

Start up your computer from the CD-ROM disc that contains system software or from the

Disk Tools disk.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy
Disk” in the section “Initializing a Hard Disk” later in this chapter.
