In my understanding, you can't just go to the root dir of your device and create it programmatically in your app, since the app is running as a separate user which doesn't have those privileges. Moreover, I doubt you can do it as a simple user manually on your phone, because you are not root either. (I am not even talking about hardcoding letter of the disk partition)

The main question here is I guess why you would need that folder. If it is for app purpose, then, you should look at this documentation:

http://developer.android.com/guide/topics/data/data-storage.html

It has pretty much all described starting from storage on your server ending with preference files.
