    Is there just one hard drive in the system?  This time it failed
    on port 4.  The previous time it failed on port 3.  The time before
    that it failed on port 0.

    Reboot a couple of times.  Is it failing on the same port every time
    or is it jumping around?

    It shouldn't even be reaching the softreset code for the ports that
    do not have connected devices.
