How to fix unreadable SD card and recover files from it?

So a couple weeks ago after trying to import some pictures from my camera only about 7 pictures uploaded and a warning came up on my computer. It said the files were unreadable and could not be read. So I bought a new sd card and took some quick shots and the same thing happened. Is this an issue with the camera or the sd cards? A friend told me their is a program to fix this issue with the sd card?
