It seems the raid was broken at the point it is now setup as regular single drives, meaning you will need to rebuild the raid. In this case since it is a raid 0, we can suggest to contact OEM (Original Equipment Manufacturer) in order to check if there is a way from the chipset, raid controller or BIOS for you to recover it.
We are following up this case, please let us know if there is any more information you require from us.
Contacted ASUS, they could not helped me.
Created a new array raid 0, deleting then my data and restarting from zero...
Not the solution I was looking for and not sure if there was a solution to my problem if my raid 0 configuration was lost...
When it comes to RAID 0 failure, the data will be lost almost for sure, instead of a RAID 1 where you can just switch one of the drives and then sync.
Not very glad to hear your information was lost, we suggest you to keep a back up daily in order to avoid these kind of situation in the future.
