Thanks for your reply. But I am afraid to say that it was useless. Now I am tellin my problem more specific:
1) It was OK to read after writing for six or seven days. After it, I don't know I wrote other things in multisession.
2)When I am accessing a picture, computer shows "Can't determine type".
3)When I am accessing a text using MS word it shows some squares on screen.
4)When I am accessing it with notepad, it is purely blank.
