Just to say a big thank you to Captain828 for his article posted May 7, 2009 in this forum. Your simply the best. I have just spent over 5 hours trawling around the internet including Microsoft and Apple tech support for a solution as to why my Optiarc DVD and Blu-ray burners had gone missing from Windows Explorer, following a disastrous attempt to install Apple's ITunes, which caused a system crash and unsigned drivers. Came across your instructions on page 3 of a Google search and with 30 mins I have implemented your solution.
