ReadyNas NV+ "Kernel Panic"

Thanks very much guys. Looks like I'll need to need to refer to the back up I have of the NAS. :(

I looking at grading to 3tb drives but I'm not sure thats possible?

Would I be able to get your opinion on the other NAS drives I have in the second NAS? Think disk 4 deffo needs replaced & have it on order.
