Our Company just bought WESTERN DIGITAL My Book World Edition II 2TB a couple days ago.
During the installation and Folder Share Permissions we encountered error to access Folder which has restriction for some users.
=Error Message+
\DataCentre\DB is not accessible. You might not have permission to use this network resources
=
I did set specific user to have access to the folder from Folder sharing permission page
Another error message says:
Multiple Connections to a server or shared resources by the same user, using more than one user name, are not allowed. Disconnec all previous connections to the servers or sahred resources and try again
I had almost the same problems and the solution was to define a user on the Mybook with an ID not equal to ANY windows user which accesses it. I also removed any other users which had an ID equal to any windows users.
