Stuck at 59% for 36 hours!

Hi

I have a 3TB drive with movies on, which started reporting errors and would not display in windows explorer.

I created a "simple volume" from disk management and did a quick format.

The drive was then visible in windows explorer, but the files were not showing.

So, I installed Recuva and set it running. It's been running now for about 2.5 days, but for the last day and a half has been stuck at "59%, 7760 files found"

I should add I am doing a deep scan (it did not recover anything with the quick scan).

Does anyone have any suggestions, or should I just be more patient?!
