As we have reported earlier, several incidents of SuperDrive failures were reported to us. The SuperDrives either responded inappropriately or not at all, after many users had installed Apple’s latest OS, Snow Leopard. We were very aware of that there was a problem, but it has been difficult to determine the scale of it. But it seems to have occurred enough times for Apple to contact a number of users who have experienced the problem of SuperDrive failures and start an investigation of the problem.
We will try to keep you updated, and provide information of potential fixes as it becomes available.
