Have you done this at any time ?
The thought occurs that most PC`s will use a 3.5" IDE port and Im fairly sure the pins are physically bigger than the ones on a 2.5" port.
Indeed. The optimum strategy for this is to steal pins from a dead 2.5" IDE disk. I did exactly the same thing to my A1200's IDE header, sabotaging an old, deceased laptop disk did the trick nicely.
In fact, if you can't find any other source of suitable pins, one of those 99p IDE/CF adapters on eBay will make a perfectly adequate donor part.
