Scans freeze?

I've tried scanning for lost files. It freezes at 0% (with a quick scan or regular scan). It had found about 300,000 files. I clicked cancel and looked through the recovered files. It wasn't the ones I was looking for, but near the date of the ones I need.

So I've tried the scan a few more times (both quick and full), but it keeps freezing at 303,164 files and 1 day remaining. Am I being really impatient or is it frozen? And if so, am I doing something wrong?

I really need these pictures. I lose 4 months of pictures that were really important to me.
