No idea.  Google for some technical documents or fire off an email to  
Asus, Intel or your RAID controller's manufacturer.

Recreating an array could be risky.  SCSI drives usually have a write- 
protect jumper, but AFAIK, there's no way to implement that with  
SATA.  You could try pulling the data or power cable after  
configuring the array but before building it.  SATA should be hot- 
swappable if you're using the SATA power plug, so there probably  
won't be any damage to your disk or motherboard.  Hopefully that will  
write to the RAID BIOS but not the disk.  I wouldn't recommend doing  
this, though, but hey, you're not me. :-)
