i bet your cables are fine, do the drives work ok? I think you are just expecting for there to be less of the ide connector sticking out of the drive and motherboard than there is.
if this is not the case, then look at the mobo and the ide connector side by side -- lots of ide cables have a blocked out pin on them and some crappy motherboards have a pin where there shouldnt be one. if this is the case you will have to find another ide cable without the blocked out pins
