My 500gb passport totally not recognized on windows 8

Hi,

     I have been using my HDD for almost one year now and it was perfectly work. But now when I upgraded to windows 8

it doesn’t seem recognize at all. Even on printer and devices menu or disk management. I don’t know what the problem is. But I,m hopeful that you can help me. 

    Thank you in advance.

does it show up in disk management?

Unfortunately no it doesn’t :frowning:
