I have a problem with my MacBook which didn't want to boot up. So I bought a new hard drive which instead of being 120gb it's a 250gb. But now I can't format it because the DVD drive on my MacBook doesn't work. Is it possible to link my MacBook via FireWire to an iMac and format the hard drive that way? Or what can I do to make the hard drive work? With out having to take the MacBook to the apple store
