Hi Peter, someone has been not letting my answer reach you. This time I 
send it to you direct.

    First, you need to get real SATA Data Cables. I do not know how you 
got your Molex cable to work. Also I have SATA and my book says that 
only one HD per SATA cable! It can't work like the older IDE drives.

    So get the real cables and I think your problems will vanish.

    And to the person who is killing my mail to this list, if your going 
to use this than make it known so we all know some mail at your whim 
will disappear!
