Apple Power Macintosh 4400 - Manual (Page 138)

m Check the ID numbers of all SCSI equipment (anything connected to the
SCSI port [g]) on your computer. Each device must have a unique ID
number. The computer itself (the main logic board inside it) has the ID
number 7. The ID numbers 0, 1, 2, 3, 4, 5, and 6 are available for additional
SCSI devices.
Also check that the chain of devices is terminated properly. For
information on setting SCSI ID numbers and terminating a SCSI chain,
see both the manuals that came with your SCSI equipment and Chapter 3
of this manual.
m If none of these suggestions solves the problem, test the disk by following
the instructions given in “Checking for Damage on Your Hard Disk,” next.
Checking for damage on your hard disk
You can test a hard disk for damage with the Drive Setup program, which is
on the Macintosh Restore CD, a CD that came with your computer.
1 Start up your computer from the Macintosh Restore CD.
See “Starting Up From the Macintosh Restore CD” earlier in this section.
2 Click the Drive Setup icon in the Launcher to open the Drive Setup program.
