20 Barracuda ATA Family Installation Guide, Rev. A
Troubleshooting
If you have installed your drive and it does not function properly,
perform the following basic checks:
Warning. Always turn off the computer before changing
jumpers or unplugging cables and cards. Wear a
ground strap or use other antistatic precautions while
working on your computer or handling your drive.
•
Verify compatibility. Verify that the host adapter and drive are
appropriately matched to each other and to your computer.
Refer to the 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 connectors and cables. Make sure all ribbon and
power cables are securely connected. Ribbon cables are eas-
ily damaged, especially at the connector. Try a new cable that
you know is good. Make sure no connector pins are bent. Ver-
ify that pin 1 on the interface cable is aligned with pin 1 on the
drive and the motherboard (see Figure 2 on page 6).
•
Verify jumper settings. Review the instructions in this guide
and in your host adapter installation guide. Make sure all
appropriate jumpers are installed or removed as necessary.
•
Check your power-supply specifications. Each time you
add a new device to your computer, make sure your com-
puter’s internal power supply can support the total power
demand. If necessary, consult your dealer for a new power
supply.
