IBM ATA-3 - Manual (Page 75)

Problem Solving
You might be able to solve the problem yourself. Before calling IBM,
you might want to try some or all of the following troubleshooting
procedures.
If your computer does not operate correctly, or the drive fails to
spin up, be sure that the colored line on the drive end of the cable
is closest to the dc power connector. On the other end of the
cable, the colored line must align with pin 1 on the IDE bus
adapter.
If the drive is configured as Slave and it is not recognized, check
the jumper settings for the master drive. The master drive might
require a jumper change to indicate Master or Slave Present in a
two-drive configuration. For more information about the jumper
settings, see “Step 3. Setting the Configuration Jumpers” on
page 2-8, or refer to the Deskstar Enhanced IDE (ATA-3) Hard
Disk Drive User's Guide Supplement.
If the master drive is not a Deskstar, see the documentation that
comes
with the drive, check the drive label, refer to the Disk Manager
online help, or call the drive manufacturer to determine if you
need to reset the jumper. For information on how to contact the
most common hard disk drive manufacturers, see “Hard Disk
Drive Manufacturers” on page 3-13.
If the drive does not operate, make sure that all power and signal
cables are securely attached. Disconnect the signal cable and
check for bent or misaligned pins. If you do not find any
problems, reconnect the cable.
If the drive does not spin up when you restart your computer, the
drive is not recognized by the configuration-setup program and
there are no error messages, try the following:
1. Turn off the computer.
2. Open the computer and disconnect the IDE cable from the
hard disk drive.
3. Verify that the power cable is correctly attached to the drive.
4. Restart the computer and listen for the drive motor to spin
up.
5. If the drive motor still does not spin up, turn off the
computer, connect a different power connector to the drive,
and restart the computer. If the drive again fails to spin up
go to “Step 2. Placing the Call to IBM” on page 3-11.
6. If the drive motor spins up, turn the computer off and
inspect the IDE cable and drive connections for damaged
pins.
7. Verify that the colored wire is connected to pin 1 on the
drive connector and is the closest wire to the 4-pin power
connector. Some connectors are keyed and will only fit one
way. Do not force the connector onto the pins. If the
connector does not seem to fit, reverse it and try again.
8. Reconnect the IDE cable and restart the computer.
