This article explains how to replace the ATA hard drive in a Power Mac G4 (Gigabit Ethernet) computer. You may also view the following procedure in QuickTime at http://www.info.apple.com/installparts .

Be sure to follow the instructions in this sheet carefully. Failure to follow these instructions could result in damage to your equipment and may void your warranty.

Replacing the ATA drive requires five basic steps:

• Turn off the computer.
• Open the computer.
• Remove the installed ATA drive.
• Install the replacement ATA drive.
• Close the computer.

Tools Required

A phillips screwdriver is required for this procedure.

Electrostatic Discharge (ESD )

Static electricity, a normal and natural phenomenon, builds up on your body as you walk around. You experience an electrostatic discharge (ESD) when you touch an object and feel a spark. ESD can cause damage to the internal components of your computer. Avoid walking around while performing this procedure, and follow the instructions carefully when you are asked to discharge static electricity.

Opening the Computer

Warning: Always turn off your computer before opening it to avoid damaging its internal components.

1. Place your computer on a clean, flat surface.

2. If you think your computer is in sleep, press the power button on the front of the computer to wake it.

3. Shut down your computer by opening the Special menu and choosing Shut Down. Then wait five minutes for the computer's internal components to cool down.

4. If you attached a security cable through the computer's lockable cover latch, remove the cable.

5. Unplug all other cables from the computer except the power cord.

6. Touch the metal PCI access covers on the back of the computer. Important: To avoid electrostatic discharge, always ground yourself by touching the port access covers before you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body, do not walk around the room until you have completed your installation and closed the computer.

7. Unplug the power cord.

8. Lift the latch on the right side access panel

9. Gently lower the access panel until it lies flat. To avoid scratching the case, lower the panel onto a soft, clean cloth.

Removing the Installed Drive

1. Disconnect the ATA and power cables from the hard drive.

2. Using a Phillips screwdriver, remove the drive carrier mounting screw. Tilt the drive carrier and carefully remove the drive from the computer.

3. Remove the carrier screws and remove the drive from the carrier.

1. Position the replacement drive on the drive carrier so that the ribbon cable and power cable connectors align with the end of the carrier that will be mounted to the chassis (the end with the screw hole).

2. Attach the carrier to the drive with the screws you removed from the original drive.

3. Align the tabs on the rear of the carrier with the slots in the computer chassis and slide the carrier in.

4. Replace the carrier's mounting screw and tighten it to reattach the carrier to the chassis.

5. Reconnect the power and ATA cables to the drive.

1. Raise the side access panel, lift the latch, and press the panel against the case until it snaps securely into place.

2. Reconnect all cables and restart your computer.

Repackaging the Drive

Repackage the drive you removed from the computer in the static-proof bag and box that you received with the replacement drive. Seal the box with the tape included, and affix the return label.
