Drobo FS fails to mount and repair does nothing

I am trying to get my drobo FS to mount after a power cut but it doesnt want to play ball. I dont want to loose the data on the drives as its all of my music and movies. Ive tried the repair function but it lasts just a minute and then says done so i can only assume its doing nothing. A restart always gives the same error. Is there anything else i can try? The logs appear to show drobo apps failing to find resources, can i remove the drobo apps if the drives wont mount? Can i simply pull the drives and manually save the data elsewhere? All help greatfully received as data robotocs wont help at all.
