Help! My Book Duo Amber Light

Hello all,

I’m new to RAID 1 so please bear with me. I recently purchased an iMac for photo/video editing and a My Book Duo 8TB for storage (RAID 1). Everything was working well until I had a hard shutdown due to a power outage. Now the Duo won’t boot. I get a flashing amber light and the computer doesn’t recognise the drive. Furthermore, the WD app keeps switching between not seeing the drive at all and prompting me to format the drives again. I just put EVERYTHING on those drives. I was in the middle of a Backblaze backup when this happened so I have no idea if everything backed up to the cloud. I’m kinda freaking out.

Am I missing something?
