I just bought an external enclousure. I know it works, I'm transfering stuff to it right now via USB. But the eSATA port on the motherboard doesn't seem to work. I tried two different eSATA cables, so that's not the problem either.
I did notice one item in my device manager that is unrecognized. It's an unknown device. Does this board require a driver for eSATA to work? I installed the chipset drivers, and everything else in device manager is recognized, so I don't think that a driver is the problem.
