Question Belkin N+ / WD 2TB EHDD

Have a question. I recently bought a Belkin N+ Wireless router which has a usb to connect my storage device to the Network and beable to access it. I connected it and set up the network. Everything works fine. It also sees my external HD which is a WD 2TB external HD. But when I go to access it, it wants a username and password to access it. I have tried every user name and password I can think of (including leaving it blank) to try and get into the hd but I am not able to. Its not the network name and password, nor my computers and the HD itsself does not have a username or password on it. I can connect it to any computer and beable to access it with no problem at all pops right up plug and play. I have searched the internet for an answer and could not find one. I dont know if this is an issue with my Router or my HD but I'm assuming my HD. So if anyone has a solution for the user name and password or a way around it or shut it off. Much thanks.

 

Update its just my computers that wont let me log into them. Tried diffrent harddrives and thumb drives i eather get the same problem, or path not found. But my PS3 can get into them every time over the network
