My internal DVD Drive is acting up in my iMac 27" 2009 i7 2.8GHz model. It has trouble reading many DVD's. Kind of hit and miss. I removed the drive, opened it up and examined the laser under my microscope and it was very clean (which surprised me). I have resurrected many Macbook DVD drives by simply cleaning the laser. I cleaned it anyway and, as expected, I still have flakey operation so there must be something else causing the issue. However, the reason for the post is.... since I am going to replace the drive anyway, I might as well put a Blu-Ray reader in there. I currently use an external Blu-Ray drive for ripping my Blu-Ray collection so putting an internal drive will save one extra peripheral hanging off my iMac. Just to clarify, I am not playing Blu-Ray on my iMac so discussions of OS X not supporting Blu-Ray playback is not applicable to me. Also, I am very experienced repairing Macbooks and iMacs so discussions about not voiding warranty and "why would you open your iMac" are also not at all applicable. What I want to know is if anyone has a specific model number of Slot Loading Blu-Ray drive that they "know" works internally in the 2009 iMac. I don't need a Blu-Ray burner since I have no reason to burn Blu-Rays, only read them. I found a Pioneer BDC TS02 TS02PB drive on eBay that they claim has an Apple label on it which seems really weird since Apple has never supported Blu-Ray so I find it hard to believe there are official Apple drives out there??? Any first hand success stories of people who have upgraded their iMac with a Blu-Ray drive would be greatly appreciated. Thanks!
