How do I setup my computer to automatically update folders onto a removable drive upon insertion?

Alexander: How do I setup my computer to automatically update folders onto a removable drive upon insertion?
I use a micro SD card between my laptop and netbook as an external hardrive for my class files. I often download files on one computer or the other without the drive in that computer. Is it possible to set my computer up so that when I insert my drive my computer automatically updates the folder on my removable drive with the folder on my computer?
