I have a (fairly) ancient MacBookPro with a Superdrive that will accept CD/DVD but then rejects them and will not read them. As a result I am using a Samsung DVD writer/reader that is sometimes problematic. Is there a way of reinstating an on board Superdrive without replacing it? My son has suggested that, like the reset button on G4s and G5s, that there may be a simple way that we are missing. Help please?
