Recuva don't work

Good morning,

first of all, excuse me for my little english, i'm italian.

I have a problem with Recuva. I had a problem with my HD (My Passport, WD) and with some research i found this program. I started it, but it's about 1 hour that it doesn't advance.

Can someone help me? It's too important for me recover the files.

Thank you, grazie.

Nicola
