No, no error lights. The only thing I did was through the Web Admin to add the Shared folder. If I go and run the NAS Navigator, it sees it but then when I click on it, it says something about a Failed Mapping and then get the Could Not Open Shared Folder - Confirm Drive Status. If I can view it on my web browser, it shows that it is operational, then why is it saying it can't be found? I really need to ensure my data is backed up. I have a RAID1 1TB array ( two 500GB drives). Firmware is 3.03
