well, in my experience, a broken cable with a loose connection can do that
too. The IDE-cables are very sensitive, sometimes, when switching drives or
just reseating the connectors one of the wires can break. And then you get
random errors, which will creep up, when the cable gets warm or cold, or the
under load or when the fans blow a little bit harder...
I solved some harddrive problems simply by changing the cables.
