I have the latest Airport Extreme model. I have a 500 gb harddrive USB connected to the Airport Extreme. Its formatted Mac OS Extended (Journaled. I have a windows laptop and a macbook pro laptop. I have having trouble sending large files greater than 2GB from my windows laptop to the USB Harddrive on the airport extreme. It keeps timing out. Small files no problems. Macbook Pro laptop has no trouble sending files of any size to the USB harddrive on the airport extreme. Why am I having trouble with Windows sending large files to my USB harddrive on my airport extreme?
