For the past few months, my Superdrive has not been able to burn any DVDs or CDs. It simply failed to recognize any blank CD or DVD, so whenever I would click Burn, it would say please insert a blank CD/DVD. So today, I was going to go to the Apple Store to have it looked at. I replaced the 4GB of Mushkin RAM that I installed a few months ago with the 2GB of RAM that came with my 2.4ghz MBP. After, I checked the drive by attempting to burn a CD, and of course, it randomly starts working. Because I thought it was the RAM (not sure how) that may have been causing the problem, I put my 4GB back in, and for some reason, it lost its ability to burn CDs/DVDs again. Why is this happening? How does RAM even affect the burning capability? This is the memory that I bought. http://www.newegg.com/Product/Product.aspx?Item=N82E16820146878 I'm using a late 2008 unibody 2.4 GHz MBP.
