Basic troubleshooting
Warning. Always turn off the computer before changing jumpers
or unplugging cables and cards.
Caution. Your drive and computer contain static-sensitive de-
vices. Wear a ground strap or take other antistatic
precaution while handling your drive.
If you have installed your drive and it does not function properly,
perform the following basic checks:
•
Verify compatibility. Verify that the host adapter and the
drive are appropriately matched to each other and to your
computer. Refer to relevant documentation for details.
•
Check all cards. Verify that all cards are seated in their slots
on the motherboard and are secured with mounting screws.
•
Check all cables. Make sure all ribbon and power cables are
securely connected. Ribbon cables are easily damaged, es-
pecially at the connector. Try a new cable or a known good
cable. Make sure no socket pins were bent when the cable
was inserted. For each cable, verify that cable-connector pin
1 is aligned with equipment-connector pin 1. The edge-stripe
on the ribbon cable is used to denote pin 1.
Caution. Do not reverse-plug connectors. This can damage
the computer and the drive.
•
Verify equipment configuration. Review the instructions in
this guide and the host adapter installation guide and make
sure that all appropriate jumpers are installed, or removed, to
suit your application.
•
Check the power-supply specifications. If new devices are
installed, your computer’s power supply may not support the
new total power requirement. Consult your dealer.
•
Verify the drive type setting in System Setup. The drive
type stored in CMOS memory by your System Setup program
must not exceed the physical specifications of your drive. Also,
