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 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 “Reinstalling System Software” earlier in this chapter).
m Check the ID numbers of all SCSI equipment connected to your computer.
Each device must have a unique ID number (the computer itself has the ID
number 7, and the internal hard disk has the number 0). Also check that the
chain of devices is terminated properly. For information on setting SCSI ID
numbers and terminating a SCSI chain, see Chapter 3 of this guide or the
manuals that came with your SCSI equipment.
m Test the disk by following the instructions that come next.
