Accessing External Drive.

[driftwood]

I have a USB drive plugged into my Router that can be accessed by my various systems.
I have done a re-format on one system and now I can't remember how to set up the connection.
I used to have a shortcut on the desktop called Mydocs which would go straight to the drive. 
I know what the address is, as I can see it on the properties of the other systems shortcut.
But It's not working for me.
Any ideas?

check the network firewall profile is set to private, a reformat will default it to public...

Thanks, got it sorted.
Problem was that the SMB box wasn't ticked in Windows features.
