Owngoal, it sounds like you removed the good disk and the disk that remains in the duo is bad, or possibly your chassis has been damaged by your power event. Do you use surge protection?

Try to power down, reinsert disk 2 (the one you have tested), remove disk 1 then power on.
If this works you will need to replace disk 1 with a good disk to re-establish a redundant volume. Test disk 1.
If it doesn't work you could try:
Inserting the disks into another duo if you have access to one or,
cloning the disks and trying the cloned disks in the duo - there is a lot of information on the forums about this.
Then backup all of your data and buy an UPS.
