Received my new Penryn-based Macbook Pro the other day, and when I loaded the install discs to install X-Code, I noticed that my Macbook would just spin for a couple seconds then spit it right out. No matter what CD or DVD I try, it just spits it out. I've read there was an issue with an old firmware update that 'killed' SuperDrive's. The SuperDrive I have in my MBP is as follows. MATSHITA DVD-R UJ-867: Firmware Revision: HA13 Interconnect: ATAPI Burn Support: Yes (Apple Shipping Drive) Cache: 2048 KB Reads DVD: Yes CD-Write: -R, -RW DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW Write Strategies: CD-TAO, CD-SAO, DVD-DAO Media: Insert media and refresh to show available burn speeds If I have no other option but to bring back to Apple, should I put back in my old RAM, which I upgraded myself after I got the machine?
