Storage card disappears when connecting in "Disk Drive Mode" with USB Cable

Well your screen shots are completely different from the first post to your last post. What did you install in between? Second, you can't navigate to your card through MY COMPUTER? Did you flash a custom rom? What OS are you running on your pc. And finally have you been able to connect your phone and use it as a disk drive before all of this? On windows 7 or at least on mine every time I do a hard reset and connect my phone as a disk drive it installs a driver automatically.
