your cable looks wrong ..
Compare to this in CPCwiki. take esp. note on the sideway diagram, which shows, you white connector is the opposite way of how it should be.
Your connectors boths facing up on the cable (2.jpg) and the should be the white facing down if the black is facing up.

hi there thanks for the help guys, yea i figured the cable was wrong - late last night i got it working using a 3inch drive and a external 5v supply. managed to get auf monty and oh mummy loaded from disk so looks like my 464 plus to 6128 plus upgrade was a sucsess!
i have now also fitted the external drive connector and was wondering if i need to do anything to make it the default A drive? i followed the guide with the wire from a pin of the internal drive but it just makes the disc access unreliable.
