disk utilities frozen and can't close down
i have an old iBook running OS9. i am trying to set it up with an external hard drive (3Tb) that i can use on a mac and pc. I plugged it into the ibook and it asked me to initialise it which i clicked on and it started to sort it out and then froze. I am now stuck with it in Disc Utility with it attempting to do something to the hard drive (that was 8 hrs ago and the hard drive is now disconnected). The on/off button is broken and i need to restart it but disk utility will not allow me to restart the computer. How can i get rid of Disk Utility and how can i get the hard drive formatted so that the mac and pc can read it.
Thanks for your help
