WTF WTF WTF, my main boot drive just won't start on my G4 MDD. Worked fine yesterday and the days before... Now I press the power button, something is going on and then the computer shuts down. Holding the alt key I was able to boot on my backup (using it right now). Wtf is going on??? No sign of failure and then boom! doesn't work. Is there a way I can repair it? Disk utility won't allow me to.
