No, it appears fine. If it ain't broke, don't fix it. Those are all ways of saying almost the same thing differently.
On second thought, are your drives sata ot eide:
There was a thread in the Ubuntu forums about the id of ide drives being called sd. I don't recall if there was any impact on the system. But if your really concerned, I would check there. However, as far as partition tables go, if they were wrongly identified, they probably wouldn't work, or work very badly.
