>Why when I save a notebook, the input output disappears? 

I assume "the input output disappears" means the "In[n]" and "Out[n]" that appears to the left of an expression after it is evaluated by Mathematica. I also assume, by save you mean save, *close* then re-open the particular notebook.

Basically, the In[] and Out[] are pointers to memory where the results of an expression reside. While you have the notebook open (before closing it) there is a clear link between the contents of memory and expressions in that notebook that have been executed. Once the notebook is closed, that link is severed. There is no practical way to re-link expressions in a notebook to the location in memory where the results are once the notebook as been closed.

>Is there any way to correct this?

Assuming I've understood your question properly, no. But I am curious as to what you are trying to do that prompts the question.
