Hi Will_H,
Bear in mind RAID 0 does not have redundancy so, any modification to the current status will break the structure and data will not be accessible.
I regret to inform you that the rapid storage software does not offer any option to see what does "error occurred" means, this may be just a SMART error and you many need to clean SMART errors through BIOS, or the drives are going defective.
Thanks
Allan
