Do not have sufficient previleges

As the admin for my My Book Live I’m getting the message whenever I  try to delete a specifc folder, I coppied over to the drive. How do I fix this?

The moderator needs to approve the image first.

the files privilege will remain on the file when you transfer to the NAS

check on the properties or log as admin and see if able to delete

Thanks for the feedback guys. I simply did a factory restore, edited permissions on original drive and then copied files over to the My Book Live. Now all is well.
