Recuva deep scan

Hi everyone, I downloaded last version of Recuva.

First of all, I selected the exact folder for scanning (for earning search time) but after 24 hours deep scan window said "1 sec. remaining", and I decided to wait for an hour message was not change. I canceled the process (I had to kill it in windows task manager) and started it again. This time I set it normal scan and same result. It is searchig for 24 hours and going on.

What can I do?

(sorry for my English)
