Mornin' I've got a Rev. A. 15-inch MBP and I've noticed recently that the SD is no longer able to read/write media. I've tried everything, DVD, CD, blank, commercial, different speeds. The SD tries to read the media but then just spits it out. I did have some success when trying to rip a Stereophonics album - disc one worked fine but disc two had problems. It worked eventually but only after inserting and ejecting many times. Thing is I got a funny feeling this problem materialised after the Leopard 10.5.6 update. The SD has been working fine up until a month or so ago. The SD is a Matshita (sp?) UJ-857 with HAEA firmware. I thought about trying to reflash the firmware but I can't find one that works with Leopard and I can't install Tiger on an external HD because the SD won't read the Tiger DVD. Just for the record the SD also has problems reading/writing media when booted into Vista. Although the Vista install DVD seems to work. Is there flashing firmware available for Windows that would work? Any ideas short of replacing the drive myself with one off of Ebay as I don't have AppleCare.
