as you can see in the above pic the ide cable has no lug, but it does have a red stripe down the side that indictes where 'pin 1' is
if it isnt marked on the body of the drive the end pin one is, then with the hole for the lug on top, the red stripe should always be to the right.

its also worth noting that the hard drive above has one pin missing dead center on the bottom row,this is normal, but if you find any other pins missing on your drive its due to damage.
