FireWire booting, as the name implies, is the ability to start up a computer from an internal or external FireWire drive.
FireWire booting is possible on all Macintosh models that have built-in FireWire ports with the exception of the Power Macintosh G3 (Blue & White) and the Power Mac G4 (PCI Graphics) models. You may need to upgrade the computer's firmware before FireWire booting will work. You can download the latest firmware for your computer from the Apple Software Updates Web site at
http://www.apple.com/swupdates.
Note: Do not confuse FireWire booting with FireWire target disk mode as described in this article: "
FireWire Target Disk Mode".
If you are unsure if your computer has a FireWire port, look for ports that look like those in Figure 1, or look for the FireWire symbol shown in Figure 2.

Follow these steps to start up your computer from an external FireWire drive:
1. Ensure the proper drivers for the FireWire drive are installed in your computer.2. Connect the FireWire drive to your computer and ensure the icon for the disk appears on the Finder desktop.
3. Install the appropriate system software onto the disk.
4. Open the Startup Disk control panel and select the FireWire disk.
5. Restart the computer.The computer should now start up from the FireWire drive. If it does not, make sure you are using third-party drivers that support FireWire booting. Also ensure that the FireWire disk mounts to the Finder desktop and that the system software was properly installed. If it still does not mount, contact the vendor of the device to ensure it can be used as a startup disk.
It has shown up before. I already had it formatted for my computer. One day it just didnt show up. I thought maybe the cables are bad becuase other external drives work on my computer too.
I HAVE THE SAME EXACT PROBLEM WITH MY G-DRIVE!
I have had my G-Drive 250 GB for 2 years and never had this problem until now. I can't find any relative troubleshooting topics on their website or in the manual. I've tried looking for it on the Disk Utility and it is not there, either.
Where did it go?
