Only two of the four can be active.
Only two of the four can be active.When one sees four ports, one expects all of them be be active in spite of "2 ports" in print. There are more than one version of this card.Also, one would expect since this is an external sata card, the external ports would be jumped to be in use. Wrong! The internal ports were jumpered.There is no name on the box or on the card. No thought if this "syba" name is the company. Hence, no support.And finally, even after switching all eight jumpers over, the external ports still do not work using two different drives and cable combinations.Btw; this does not appear to display in device manager in w7 after you load the driver.
