I figured I would post for help here as Patriot Tech blew me off. I just hope I can find a solution.

4 x 2TB WD enterprise class drives running Raid 5
Win 7 Ultimate x64

I expanded the Raid volume from 3TB to approx. 5TB, leaving a little storage in case I wanted to set up an iSCSI partition. At this point I can no longer write any data to the NAS, yet I can read existing data already stored on the NAS just fine. When I try to copy new files to the S4 I receive an error message "You require permission from Unix User\Root to make changes to this folder".

I am not a programmer, but I do know how to get around a computer now and again.

Any help would be greatly appreciated as this issue makes the S4 unusable at this time.
