If you don't get a definitive answer but you really want shorter IDE cables, you can, provided that you don't need the secondary connector, purchase cables that only have one device connector. It might be better to purchase new cables, since you'll most likely be doing it anyways once you find out that the the cable doesn't work after chopping the port off, and have some backup IDE cables incase anything in the future goes wrong. I don't know, personally, I like to keep a couple of known working IDE cables handy.
