Hi I am having a similar problem with my Vodafone Ultra Hub. I have connected my USB HDD to the router, turned on Samba and connected to the network drive on my Macbook and it shows up in Finder, allows me to add files and remove files but it only shows up as a 200Mb drive (its actually 1.81Tb) and doesnt show any of the files that are already on it. Any idea why it's doing this? Its all working perfectly, just not letting me access the main drive. Its almost like I'm accessing a small partition on the drive but I havent made any partitions on the drive. Help please!!
