I followed the steps in the wiki and created the share, but I can't move any files there, it tells me I don't have permission. I verified that "read+write" is selected. I even changed it to "read", saved it, then changed it back. I'm stumped.
I have a 2TB WD Mybook attached to the A+. Formatted it NTFS and then connected it to the router directly after.
EDIT: When I map the share, I see "usb" and "usbs". The second one seems to be for the bitorrent client, and I can create files in the three folders in usbs\sda1\transmission\. The other folder under share, which is "usb" has a subfolder called "My Book". I can't create anything under the "usb" folder.
