lost data stored
I bought about 3 weeks ago a WD 4 Tera and 2 days ago I tried to open some data stored but I couldn't,
They are still in HD but doesn't appear when I tried to open them . What can I do?
I'm using windows 7 ultimate. I stored about 1,5 tera . I suppose data stored are still in HD because
the data storage is exactly the same.
