The hard disk icon does not appear on the desktop.
If you don’t see a hard disk icon on the desktop, try the following:
mIf the hard disk is internal, shut down your computer, wait at least 10
seconds, and then turn it on again.
mIf the hard disk is external, make sure that it is turned on and that its cable
is connected firmly; then restart the Macintosh.
mCheck the ID numbers of all SCSI equipment connected to your computer.
See the manuals that came with your SCSI equipment for information on
setting SCSI ID numbers.
mIf the hard disk is your startup disk,start your computer using the
Disk Tools floppy disk or (if you have a built-in CD-ROMdrive) with the
CD-ROM disc that contains system software. (For instructions on how to
start up your computer from the CD-ROM disc, see “Starting Up From
a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this
chapter.) Then follow the instructions in “Repairing a Damaged Disk”
later in this chapter to test your startup hard disk and repair any damage.
If repairing the diskdo esn’t help, follow the instructions in “Installing or
Reinst alling System Software” later in this chapter to reinstall system
software on your startup hard disk.
Icons do not appear correctly on your screen.
You need to rebuild the desktop—a process that helps your Macintosh keep
track of files and folders on your hard disks. For instructions, see “Rebuild
Your Desktop Regularly” in the section “When You Run Into Trouble” earlier
in this chapter.
If icons do not appear correctly after you rebuild the desktop, restart your
computer while pressing the Shift key to temporarily turn off system
extensions. When you see the “Welcome to Macintosh—extensions off”
message, release the Shift key and press the Option andxkeys until you see
a message asking if you want to rebuild the desktop.
