Problem with IDE cables and interface

[Gulliver]

I have found that when trying to connect my DCE bufered IDE interface, I cannot do it because the female IDE conector at the cable, has one pin hole covered.

So I guess I need to bend a pin, am I right? Which one should I bend?

Please have a look at the picture, it is self explanatory.

The cable is keyed on both sides. I will try to see if I can remove the key.
