Unix User\nobody

I have 3 files located in my Shared Videos that I am trying to cut and paste to another folder and it says i need the permission of Unix User\nobody.  How do i fix this?

Drive: MyBook World

OS: Windows 7

Hi, I am having the same exact problem, can you tell me if you figured it out?

I have a large amount of files that were copied directly to the Download share from my Windows 7 computer which now cannot be deleted.  I get the same message that says I need permission from Unix user Nobody. 

Why does this unix user have permissions over files I created on the share??   And how do I regain control of these files?   I can’t find a way to delete them through the WD My Book interface either…any help on this one? 

Thank you!
