You can try the sd card in another cam but chances are you have a corupt disc and all is lost , you will have to reformat the sd card before you can use it again , you might be able to do this from your cam program , under tools probably , if you can't find it look in help under index , if its not in your program you will have to use a sd card reader and right click on the removeable disc in My computer and select format. I have had to do this with ipods , cams , cellphones ,about anything that has a disc in it
