Over the past week I've been having intermittent problems with my MacBook Pro's SuperDrive. I don't read or write from CDs/DVDs very often, but recently the drive has been accepting disks sometimes and other times it just beeps at me and spits them back out after a few seconds. A call to Apple Support and an SMC reset helped for about one day, then the problem came back. The support representative said that the drive could be slowly dying. Has anyone else had this issue in the past? I'll be bring the MBP to the Genius Bar this week (my warranty expires in less than 40 days and I want this cleared up).
