Hello Dame,
Recovering lost files once they have been overwritten is pretty much impossible. There are some companies that say they can do it, but most are just saying they can recover deleted data but not overwritten data. There are some places that can get data that has been overwritten only once.....but it is incredibly expensive.....into the thousands of dollars.
That program you used probably found the pictures that haven't been overwritten by new data. The program we use at my tech shop is called getdataback (ntfs version if you are using XP or Vista). It can be found here -
Data Recovery Software - File System Utilities It retails for $79 dollars. But again, this will only recover deleted data that hasn't had new data copied over it.
At this point you shouldn't be using the computer at all if you are going to try to recover lost data. Every bit of new data you add on there....even temporary internet files....are going to be copying over your old deleted data.
If the pictures are worth a few hundred dollars to you, you can bring the hard drive to Best Buy for their data recovery service. They send it out to their service center to have it done, but I believe it costs 5 or 6 hundred dollars.
Hope that helps!
