Cache Drive "Unmountable: not mounted" after reboot

[frostrunnermobile]

As the title says, here's as much info as I can gather.

attached diagnostics and smart test after array started.

 

"root@FrostyUnraid:~# btrfs restore -v /dev/sdc1 /mnt/disk8/recovery
No valid Btrfs found on /dev/sdc1
Could not open root, trying backup super
No valid Btrfs found on /dev/sdc1
Could not open root, trying backup super
No valid Btrfs found on /dev/sdc1

I pretty much only had appdata and system folders on there. But i'd like to try and recover if possible.
