I cannot boot form external harddrive
iMac g5 20" tiger 10.4.11
apple store diagnosed a problem as bad hard drive
i had them remove the drive as i have an external drive firewire 400 that i can boot from. At first the mac could not recognize the external drive so i held down option key during start up to choose disk,after 4 or 5 tries it finally did boot. i used system pref to set start up to the external drive. i turned it on and off 5 o 6 times and it worked properly. Ran it for 3 days (without shutting down) no problems. shut down it as i was going to be away for 3 days. when i came back and restarted it would not boot from the external drive. tried reseting pram, booting from tech tool disk that came with my apple care package(got to apple on screen with a "no"symbol, and a different hard drive no good , Booted from system install disk(that came with the g5) ran system profiler which did not show anything in the fire wire port.
