I need to repair my hard drive.. I bought the Mybook 500GB external hardrive and cloned my hardrive to it. However, when I try to start up from it I can't. I hold down the option key it only shows Mac 10.4.11 HARD DISK and the E drive but not the external hard drive. IT is fire wire. I held down the M key no luck, the C key no luck and the option key, no luck. I went into system preferences and clicked "Mac OS X 10.4.11 on Hard disk boot" which is what I named it on the external hard drive. When I restart it starts from the hard disk internal???????? MOS X 10.4.11 Powerbook G4 The icons show up on my desk top and I can access them but they just don't show up as an option to start up from. I am not sure what I am or am not doing right! Any help, I would be grateful.
