bogus 0-byte Vol created, real volume unmountable

My Mac mini Server restarted for some reason (perhaps a brief power outage) and now my DroboPro is presenting itself as TWO separate hardware devices.

The Dashboard still only shows the one volume I had created, and it still reports that all is well–EXCEPT that it has renamed the volume to ‘Drobo’ from what I had named it, and attempts at renaming the volume using Dashboard all fail.

The first of the two hardware devices is reported by Disk Utility and System Profiler as being an unpartitiioned 0-byte device which is, of course, unmountable.

The second device is reported by Disk Utility as my DroboPro with my original, correctly-sized, correctly-named volume, but it is unmounted, unmountable, and Disk Utility cannot repair it. I haven’t located my DiskWarrior CD yet to try that, but this seems like a much more significant issue.

The report from System Profiler is at the end of this message. Any ideas?

What happens if you go to the “Go” menu in Finder and do “Go to Folder” and put /Volumes.

Sometimes the Mac will mount a phantom volume if there is a crash.

I had this problem happen to me and that is what the problem was.

My volume would mount with a 1 after it and cause all sorts of issues.

I deleted the false mount point in the /volumes folder and rebooted. All was well in the world.
