We have new information on the recovery process. The array was not able to be rebuilt from the cloned drives due to logical partition errors so the recovery service has performed a full recovery, restoring everything to a single 6 tb drive that the engineer said should boot and that all the files are intact. The additional costs, less the $2302.56 we have already paid them, comes to $2510. We currently have $3432.88 which would make our budget very tight (we still have hosting costs, etc).
Thank you very much for your patience and support!
