It sounds like the drives may not have been unformatted. Can you connect them to a Windows PC and see if there are any partitons on them? If there are, delete them. If there aren't, run vendor diagnistic tool to see if you got a bum drive.

After I was getting the corrupt root error I checked both drives via a USB caddy in a windows machine to check for a previous format. They were both functional but unfomatted (both are new drives). I decided to add a Windows format to check if defective. They both show up just fine and usable in Windows. I then deleted that format and re-installed in the NAS. Same result with corrupt root error.

One option is to do use the boot menu to do a factory default. See pages 14-15 here: http://www.downloads.netgear.com/files/GDC/RNDU2000/ReadyNAS_Ultra_UltraPlus_NVX_Pro_HW_en_8July11.pdf
Another option is to use either Seagate's Seatools software or WDC's Lifeguard software to zero the drives. Lifeguard has an option for a "quick zeros" test - that is much faster than zeroing the entire drive, and is enough to remove all traces of any partitioning.

I have tried the factory default option several times in the boot menu. It always comes back as corrupt root.
I also used to Seatools to zero the drive(s). Still comes back with corrupt root error.

Welcome to the Community!
Have you tried doing OS reinstall and if it did not work then USB recovery for OS 4.2? There might be a problem with the OS. If this still did not resolve the issue then contacting Paid Support might be the last option.
