Hello! I've a Linksys E4200 Router and I have a External Hard Disk connected to its USB Port. The Drive is HFS+ And it works perfectly. I can access it through all of the Macs we have at home. I can read all of the Files, and I can also Copy files to the Drive from all of the Devices. But the strange problem is: I can't move Folders and Files around inside the External HD. So when I have for example a MKV file inside the Root of my External HD, I can't move it inside /Root/Movies/ Any idea?
