What exactly do you mean, you can't open pictures?
when i check partition i see my all files and they have their own icons i open them by "windows picture and fax viewer" it tells : no preview available and Nero photosnap viewer tells : file is not exist
this problem is exist for other types such as text and doc files too
when i open a text file in this partition it tells it is not exist
when i copy new files such as picture or text or video to this partition now . i can open new photos but i can not open old photos before installing windows XP
