Hey, just yesterday, I transferred some files (music) to my Samsung Galaxy S' USB Storage. [running Gingerbread]. Ever since, the pictures in the gallery have failed to appear even though they are intact when I connect my phone to the PC or in my phone's File Manager. I can't even click pictures from the camera or take screenshots(Unable to capture screenshot). The gallery shows a "No SD Card" error, even though I don't use an external SD Card. Just the 5GB USB Storage on the phone. Even my whatsapp messages roll back to when I last transferred the files. Why so and how can I fix this? It seems like my default phone storage has shifted to a non-existent SD Card and there are no settings I can find to fix that. Please help.
