Mapping to Extend volume

I have 2 (1) TB drive in spot 1 and 2 and 2 320gb in spots 3 and 4.

I created a folder in the datavolume and can access it and map to it just fine. I created a  folder in the extendvolume and only gave permission to me, with admin rights. The extend volume shows in in the lists but I can not get it to map. I used WD discovery and WD link and both just show the datavolume folder.

How do I map to the extend volume??


Are you able to manually access the Extended Volume of your WD My Book World Edition II by using a direct Windows path such as \NASNAME\ExtendedVolume ?
