Greetings Thomas ( + )!( + ) The first thing that I would do is to insure that each dive operates independently of the other other drives. You say that the 250Gb drive is recognized but the 160Gb is not. If your reverse the position of the drives is the 250Gb drive still recognized and the 160Gb not? If so then the drive is more than likely not functioning. If the 160Gb is recognized and the 250Gb isn't seen then you might have a bad cable or your motherboard might be bad. Or perhaps the drives that you are using need jumpers that tell them to operate in the cable-select mode. What are the make and model of the 250Gb and the 160Gb drives?
