imac not seeing firewire 400 devices

by grip--2008 / January 7, 2010 11:30 AM PST

HI My intel 20" Imac, running snow lepoard, will not recongize my external hard drives via the firewire 400
port. It will via USB but neither firewire 400 or 800. I called Apple a few times. Apple replaced the internal hard drive. AN authorized service guy says, the external drives are fine. He hooked up my external drives to three other macs that did not see them either. I have tried a firewire 800 to 400 cable, restarts, reset PRAMS, The imac passes all Tech Tool tests. All this started when I ejected the external hard drives from the desktop and unplugged the power and firewire before vacation. Came home plugged them all in, nothing. Any ideas or similiar experiences?

Peace, Sven
