   #1 is a matter of checking the USB storage device. Not a drive letter. You   
   can use WMIC tool to list the DISKDRIVE devices. Use the SerialNumber field   
   to identify the storage device.   
      
   The storage device will not be listed if it's not connected, or has been   
   "safely removed" via icon tray menu.   
      
   If its connected but is locked (i.e. #2), the storage device will be listed   
   but its drive letter will either don't exist, or is not accessible.
