Just wondering if this is normal. I just got my 12" pb yesterday. On every start up (or wake from sleep), the combo drive makes a strange noise as if it is trying read it. Is this normal? It is as if it is trying to search for a boot disk or something but can't find it. I put in a dvd in there and it plays. I haven't tried to burn any cd's on it yet. I have a slot loading G3 at home and it doesn't do that when it starts up or wake from sleep. Any input is welcomed. Thanks.
