Yep, restarted with the firewire drive on. The drive mounts on the desktop just fine, but when I apple-click on my user name at the top of my home folder and see the path, "Volumes" is grayed out, even though I can get to the drive.
I went to the Volumes folder vie the "go to folder" menu and there is this:
Macintosh HD: internal drive
Firewire: name of my firewire hd
Firewire 1: not sure what this one is
poulh: my username
