If you can start up from your Power Computing Mac OS CD-ROM, follow
the steps under the previous section,
Flashing question mark on start-up on
page 37.
A hard disk icon does not appear on the Mac OS desktop
■
If the start-up hard disk is internal, restart your machine.
■
If the hard disk was recently installed, verify that all connections are firmly
in place and that the drive (if it is a SCSI drive) has a unique SCSI ID.
■
If the hard disk is external, verify that it is connected and terminated
properly, and that it has a unique SCSI ID. Make sure that there are no SCSI
ID conflicts. See
Using SCSI devices on page 16 for information.
■
If the disk is your start-up disk, start up your computer from Power
Computing Mac OS CD-ROM. You can remove the internal drive from the
startup sequence (and force your system to boot from the CD-ROM if you
have it in place) by holding down the
shift , option ,
x
, and delete keys
(the
x
key is also called the command or

key on some keyboards) when
you start up.
Use the Hard Disk Toolkit PE utility on your CD-ROM drive to mount the
hard drive; see
Mounting the hard disk, starting on page 49 for details.
Use the Disk First Aid program to check and repair your disk. (See the Disk
First Aid entry in the Mac OS Guide for instructions.) If repairing the disk
does not solve the problem, reinstall the system software as described in
Using the System Software installer on page 51.

This can indicate a damaged disk or one that is not initialized.
■
If a floppy disk has never been used, it may not be initialized. See the
Mac OS Guide for instructions on how to initialize disks.
■
If the disk is damaged, try using the Disk First Aid program to repair it. See
the Mac OS Guide for instructions about using Disk First Aid.
