I am not sure I am reading your post correctly, but it appears that you have a RAID array and you set it as a non-RAID array. That will render the drives unreadable as the data is spread across all drives (presuming it is a RAID 0 array as indicated.)
You will need to reset the RAID array and copy the data to another drive or media and then start over.
There is NO way to recover data from a striped RAID array if you break the array.
All the data on the array is split, literally byte for byte, across both drives.
You must re-establish the array. Set the array back for RAID 0, or striped, and see if the controller will/can re-establish the current array. If you haven't messed with the drives too much, the array should start working again.
