Mapping (non-Airport) network drive problem

Hi all, I am a new mac user and i am having a problem mapping my Seagate external drive which is connected to the network via USB on my wireless router(Linksys EA3500) I have a Macbook pro 2012 running Mountain Lion.

I have tried to go to connect to server and type in the address of the drive(smb://192.168.1.1/name of drive) but get a message saying there was a problem connecting to "address of server" please contact admin. This drive was able to be mapped on a Windows system and worked fine. Does the drive need to be formatted to be read by a Mac?

I should mention that when i go to Finder, it does see the drive as a Free Agent drive but it has no folders.

Any help is greatly apppreciated.

Really? No replied yet? Someone has to know. please

When you look at the drive in Finder, do you log in? You likely have to enter a set of login credentials. This would explain why you can only see a portion of the contents (or, in this case, none).
