I have tried to install my new Hitachi Deskstar 160GB hard drive in my iMac G3. I have made sure all the connections and settings are properly in place: jumpers, power and ide cable. However, when I turn on the computer it refuses to recognize my hard drive. I've tried going to disk setup on the Mac OS 9 installation disk but it still cannot detect my hard drive. I got it off ebay second hand so I'm wondering whether it's dead.
