I just bought a SanDisk TransFlash card (microSD) for my cell phone. When I put it in my computer to load data, it asks me if I want to format it. I say yes, then it tries to format it and says it can't. I think it's an em bay drive. I tried to put songs on it, it doesn't work. I tried to put pictures on it from my phone and view them on the computer, that doesn't work either. Help?
