FireWire Target Disk Mode
If you have a problem with your computer that prevents you from starting up or if you
just want to transfer files between two computers, you can use FireWire to connect your
computer to another computer and then have it appear as an external hard disk on the
other computer.
To connect your computer in FireWire target disk mode, follow these steps:
1 Use a FireWire cable to connect your computer to another FireWire-equipped computer.
2 Start up your computer and immediately hold down the T key.
Your computer display shows the FireWire disk mode indicator, and the computer internal
hard disk icon appears on the desktop of the other computer.
3 When you are finished transferring files, drag the computer hard disk icon to the Trash to
unmount the drive.
4 Press the power button on the monitor to shut your computer down and then disconnect
the FireWire cable.
