New ultra 11 4.0 gb

Hi, I purchased a short time ago a Sandisk Ultra 11, 4 gb card , after repeated attempts formatting in my slr EOS5D3 camara and others, it fails to work, any suggestions would be apreciated ,

Have you tried formatting it in your computer, maybe with the SD Association’s Formatting utility?

Hi, I use windows 7 and the download I find as you gave is for XP,  I will looke elsewhere


I don’t know where you’re looking, but the page I see says it’s for _ all _ versions of Windows, up through and including Windows 8.
