TechTool Protege doesn't fit into the FireWire port on my computer. What can I do?

Because of the way the ports on a few Macintosh models are designed, some cables and devices (such as flash drives) may not fit directly into the ports. In that case you may need to obtain a FireWire extension cable. These are available from most computer and electronic stores. Also, many FireWire hard drives have two easily accessible FireWire ports. If you have such a drive, you can plug the drive into the computer and then plug TechTool Protege into a FireWire port on the drive.
