Trying to plug it in, and here is the error: Unable to mount My Passport Error creating mount point `/media/jianyue/My Passport': Read-only file system
Check to make sure that '/media/jianyue' exists. I assume that jianyue is your username. Ubuntu seems to have a bug in that they now want to mount these removable drives in /media/'username' but it does not automatically create it...
So, I think this should work for anyone for their own user account:
You would need to have administration privileges to be able to do execute these commands. You should end up with the directory /media/jianyue created and owned by jianyue.
