Hi Neil, as you have noted, most CF adapters out there have the IDE connector mounted in a way that is 'inverted' from our point of view, The CF adapter IDE connector should have the locating bump on the component side, *Most Don't.* John uses a adapter made by SyBa, these are available on Ebay if you search for 'syba cf adapter' alternatively you can run a IDE cable out to a Startech 3.5" Drive Bay CF adapter as I have done, these work fine also. http://www.ebay.co.uk/itm/StarTech-com-CF-Card-Reader-to-IDE-Adapter-35BAYCF2IDE-/111342844456?pt=UK_Computing_ComputerComponents_InterfaceCards&hash=item19ec8cfa28#ht_1133wt_1171 Regards David Fry
