Unfortunately, RAID 0 (Stripe) and variations (Span) do not offer fault tolerance in case of an individual disk failure in the array, which means stored data is potentially unrecoverable by RAID array design. For this very same reason it is highly advisable to keep an active backup (Defining “backup” as parallel copies available in separate locations) at all times in order to minimize potential data loss in a RAID 0 or a Span array configuration.
I would suggest contacting a professional and specialized data recovery company for analysis and examination. You can obtain a list of preferred partners from the following link:
