Hi, Udisk is the built-in memory of the phone. A.
When you plug your flash drive into an available USB slot, a window should automatically pop up saying " view files or folders", click on it then drag n drop your documents into the opened window. If the window does not appear, click on start menu - my computer("computer" in vista) and look for a drive that's not your hard drive (usually C), and not your CD/DVD drive, in my computer, my Flash drive shows up as "UDISK F". Once you find your flash drive icon, double click it to open a new window. Open your documents folder and drag n drop the documents directly into the opened window. Abra Cadabra you are now a computer genius (According to my Mom).
