Corrupted, do not mix used disks and cold boot up. In most cases, problem may be solved by OS reinstall with
optional NAND recovery. Contact tech support before taking actions.
How do you do this optional NAND recovery?
I suggest you try booting in read-only mode using each possible set of three drives and see if you get better results.
I think what they call "NAND recovery" in the ancient documentation is what we now call USB recovery.

You can't with the NV+. But you can boot it up skipping the volume check (which should be good enough for the purpose here). See pages 23-24 here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf
Another option is to try removing all the disks (labeling by slot), and then try to do a factory install on a spare disk (which will be reformatted). If that works, then that will tell you that a USB recovery isn't needed.
