That's one possibility.

I haven't used firewire at all, so I can't say.  But it would seem
that if you stop Vinum and start it when the firewire drive is up, you
should be able to confirm this yourself by restarting and seeing what
happens.

I'm sure there is, but first we should determine whether that's really
the problem.

That would be a workaround.  It should definitely work.
