Unless the rotor has worn through to the fins, it shouldn't be causing any noise. Based on your description, it sounds like a wheel bearing. Does the sound chance when you turn?
As far as the abs light, have the computer scanned to determine where the problem is coming from with that. Again, unless the sensor has come loose and is rubbing something, it wouldn't be making the noise either.
Let me know what you find.
