Hey guys!

I've had this problem for awhile and have done a fair amount of troubleshooting and searching for an answer. So far no luck.

My 2010 Mac Pro only has firewire 800 ports. I can no longer mount a drive on any of these ports. It used to work. When it stopped working isn't clear. I run an audio interface thats firewire 400 with an adapter and it works fine. If I use the adapter with my firewire drives they mount(as FW400). These drives mount via USB as well.

Since the drives work, and the ports seem to function if their doing FW400, it seems like a software problem. I've reset pram, repaired permissions, etc. ad nauseum with no results. All testing done with just the one device on firewire. Nothing else plugged into the machine aside from mouse, keyboard, and monitor. I used to work in Quality Assurance for a tech company, so I'm pretty good at tracking these things down. Hopefully someone can help me, cause I'm stumped!

Running latest version of Snow Leopard.

Thanks!

Mike
