The Combo Drive in my Sister's MacBook has been acting up for the past couple of weeks. It will not read music CDs or video DVDs. It will however read regular software CDs and DVDs.
That seems to indicate to me that it's not necessarily a hardware problem since it has no problems with some things but refuses to play others.
Any ideas? I haven't yet tried an Archive & Install, mostly because I'm not sure if it will even help.
