FireWire Target Disk Mode allows two Macintosh computers to be connected to each other using a 6-pin FireWire cable, resulting in one computer's desktop showing both hard drives.

Host:
The computer that will be mounting the second hard drive is also called the Host machine. In the following example, the Host machine is a desktop PowerMac G4.

Target:
The computer that will be connecting to Host machine is called the Target machine. In the following example, the Target machine is a Titanium PowerBook G4, a.k.a. TiBook.

1. Make sure the Target (TiBook) computer is turned-off.
   Important: Disconnect all other FireWire cables and devices.
2. Turn on the Host (Desktop) computer.
3. Plug in the 6-pin to 6-pin FireWire Cable into both the Host and Target computers.
4. While holding down the "t" key on the Target's (TiBook's) keyboard, turn on the Target computer. Continue to hold down the "t" key until you see a FireWire icon floating on the screen
5. The icon of the Target's (TiBook's) hard drive will appear on the desktop of the Host (Desktop) machine. At this point, you can transfer files or copy directories to and from both drives, just as you would with any other disk, i.e. a Zip Disk.
6. Once you've completed copying files, drag the Target's (TiBook's) Hard Drive to the trash can to un-mount the volume. Alternatively, you can click on the Target's (TiBook's) Hard Drive once to select it, then using the Menubar, go to File/Put Away.
7. Press the power button on the Target (TiBook) computer to turn it off.
8. Unplug the 6-pin to 6-pin FireWire Cable from both machines.

When you hold down the "t" key and turn on the Target (TiBook), the screen will have a floating FireWire - similar to below:

On the Host (desktop) machine you will see two drives mount on the desktop, the second drive icon belongs to the Target (TiBook).
