All of a sudden (while I had it mounted) my external firewire drive lost connection with my computer. I've rebooted several times and unplugged and plugged it back in. Sometimes it will recognize it for a brief while and allow me to use it then all of a sudden it disconnects. Other times I can't get it to see it at all. What's strange is that it works perfectly fine on my iBook. I've tried it on the G5 under a different (clean) user, but same result. Any ideas?????????? Thanks.
