I had the same thing a few days ago.
hook up the drives to a linux machine and do the following to mount the your data
sudo mdadm --assemble --scan
look under /dev/md/ wich raid volumes where found
your system should have found 3 volumes. one is the os of the nas one is swapspace and one is your data volume.
create a directory where you mount your data volume in that folder (REPLACE NAME_OF_YOUR_VOLUME with the name you got from the ls command)
mkdir /media/md0 sudo mount /dev/md/NAME_OF_YOUR_VOLUME /media/md0
now you can backup your data. After the backup destroy the partition table of all drives. When you plug them back into the nas the nas rebuilds the OS and creates a new raid 5 volume where you can put your backuped files

I had the same issue with all 4 drives showing failed, sent WD support an email but nothing back yet.
I don't know anything about linux, I guess there is no order the drives need to go into the system for software raid.
is there anything you need to do in the linux to get it to detect there is a raid 5 volume?
Will any Version of linux do.. such as "mint"
