I really need some help.
My Powermac suddenly stopped recognizing external, firewire storage devices (external drives or compact flash card readers). The devices work on my powerbook, so it is the Powermac that is the problem. Reboting several times has not solved it. I plug in the drives or card reader , but they never pop up on the desktop or finder. The powermac does recognize the secoind internal hard drive.
How can I reset the powermac's ability to look for external firewire drives?
I have had the machine for about 9 months and it worked fine with external firwire storage devices until yesterday. It just suddenly stopped recognizing them.
Disk utility does not even see or list the external devices when they are plugged in.
Running OSX Tiger on dual G5
Thank you!!!

Hrm ...
I would delete everything in /System/Library/Caches, /Library/Caches, and /Users/You/Library/Caches. Also remove the two files /System/Library/Extensions.kextcache and /System/Library/Extensions.mkext. Reboot. Give it a go again.
Oh, just a tip ... the next few times that you reboot and launch applications will be pretty sluggish. OS X will rebuild all of those caches and things will get snappy again, so don't worry.

well....i had that problem before...
and what i did is replace the firewire cable...
the one that came with the actual hard drive might be of poor quality and easily breaks...
then again...it wouldnt explain why everything else wont connect....unless your using different cables for the laptop and the desktop
but dont make this a reason to hate on the power mac...
you must love it so it will love you

How do you rest PRAM? I've never heard of PRAM.
Thanks for all the suggestions.

Never argue with an idiot. They'll drag you down to their level and beat you with experience.

I have deletede all the items in the cache locations as suggested, and reset the PMU and nonvolatile RAM as indicated in the link above.
But still no external drives of flash cards/readers being recognized.
Any other ideas? Thank you!

New Clue:
USB connections to external drive works. Just not Firewire. Though none of the Firewire ports work (it's not just a matter of a single firewire port going bad).
It also seems other devices (the printer) connected via firewire are not working.
Do you think this is a hardware-gone-bad issue, or an OS/software issue regarding the firewire port control?
Thanks again.

I would blame the Firewire cables then, or the ports themselves. Turn the system off and see if you can give the inside of the ports a quick cleaning with a small Q-tip and rubbing alcohol. Do the same to the ports on your devices. Try a cable from a friend.
