Datavolume doesn't exist ! message

I have had a similar problem with a 8TB WD Share space after 8 weeks.

WD have failed to provide any information on this issue and I may have lost 2 years worth of scientific data thinking it was safe on RAID5.

Has anyone come up with a solution for stripping data off the drives or is it gone forever?

I am giving WD 14 days to come up with a solution to this known problem otherwise I will be lobbying the Universities over here in the UK to blacklist them for procurement purposes
