Permanent Folder on Mac


I bought  2T MBL last week. I have a PC at home and a Mac (Lion 10.7.3 OS) at my lab. I use WD 2go at the lab. So far I connected the MBL through the web site and later opened a Finder folder which I placed on my desktop. This Folder only lasts for a day (as long as I keep my mac working before shut it down). Is there a way to establish a permanent connected folder on my desktop or at least a folder which will ask for a password in each first daily use?



If you are referring the folder on the NAS you can map the MBL and click the connected servers box
