I can download music and mpeg,mpg files and watch them on pc and was able to transfere them onto the sd card in my ipaq by dragging them in. Now every time I try to do this anything I try to copy wont go and a box comes up with
The file is read only memory, write protected disk or currently in use by another application.
This even happens when i try to copy file Ive already copied

Anyone else had this problem

Many thanks
