Action
Remove the drive that is indicated by the diagnostic tests; then, run the hard disk
drive diagnostic test again. If the remaining drives are recognized, replace the drive
that you removed with a new one.
Remove the hard disk drive that was being tested when the computer stopped
responding, and run the diagnostic test again. If the hard disk drive diagnostic test
runs successfully, replace the drive that you removed with a new one.
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.
Run the diagnostic SCSI Fixed Disk Test.
Note: This test is not available on computers that have RAID arrays or computers
that have IDE or SATA hard disk drives.
Action
Make sure that:
v All cables and cords are connected securely to the rear of the computer and
attached options.
v When the computer is turned on, air is flowing from the rear of the computer at
the fan grille. If there is no airflow, the fan is not working. This can cause the
computer to overheat and shut down.
v Make sure that the SCSI bus and devices are configured correctly and that the
last external device in each SCSI chain is terminated correctly.
