The hard disc was doing the terminating and was connected to an IDC
connector right on the end of the cable. ANy stub after that would be
excess IDC cable past the crimp point no more than 1mm i.e. half the
width of the IDC connector.

With this same setup but with the harddisk not terminting the cable
the problem went away this is the opposite of what I expected.

Which is what I'd expect without termiantion not with it.
