Recovering 2 x 3TB disks in RAID 0 - My Book Live Duo

Hi! I have a My Book Live Duo (NAS from Western Digital) with 2 disks (3TB each) (as far as I can remember) on RAID 0. Due to a power shortage, one of the disks (disk 2) is reporting a failure. I believe it is a logical failure, once it's working (no strange noises) and I can see partitions on GParted, but the main partition (2,7 TB) figures as "unknown".
Code:/dev/sdb3 primary linux-raid 489MiB raid
/dev/sdb1 primary linux-raid 1.91GiB raid
/dev/sdb2 primary linux-raid 1.91GiB raid
/dev/sdb4 primary unknown 2.72iB raidDisk 1 looks ok
Code:/dev/sdc3 primary linux-raid 489MiB raid
/dev/sdc1 primary linux-raid 1.91GiB raid
/dev/sdc2 primary linux-raid 1.91GiB raid
/dev/sdc4 primary linux-raid 2.72iB raid

(the data above I got from a Linux station)

I sent to a data recovery company, but they charged me a fortune...

Is there a way to mount these 2 units as RAID 0 on a UBUNTU server? The discs are already installed...

Running fdisk on UBUNTU Server I got:
Code:sudo fdisk -l | grep sd

(in this situation, the discs are /dev/sdc and /dev/sdd)

Also, running mdadm I got:
