Over time, my 2007 Mac Mini's optical drive (Matshita CW-8124) has developed a problem reading DVD media (read-only and recordable). I was thinking about using this drive as an upgrade: http://www.cdfreaks.com/hardware/product/965-Optiarc-AD-7630A.html Has anyone else here swapped out the Apple-supplied optical drive for a better one? I know with past versions of Mac OS X, there were restrictions on third-party burners but I think such restrictions are non-existent these days. I was still curious if there would be any compatibility issues with using this particular drive. I will be using iDVD 8 and Toast 9 to name just two. I am also very pleased with the Pioneer DL-burner in my new 2009 Mac Mini. I love how it is totally silent except when media is actually inserted. The Matshita drive makes this silly noise when the Mini is powered-on and wakes from sleep. I do not have the Pioneer model number in front of me right now. I am confident it would be a perfect candidate to upgrade the Matshita drive but I am concerned about price and availability with that one. I will research it later. Your thoughts are appreciated.
