Help needed - RAID recovery from Power-fail

This is strange... For an RAID-5 array you need 3 disks at least. You 
can not have RAID5 with just two disks.

Are you absolutely sure it was an RAID 5 array? If that's the case, the 
array was already in degraded mode..... It is not possible to recover 
data from an RAID5 array if you have just one disk. Therefore u need at 
least two disks...
