I have a MacBook Pro, 2.2GHz Intel Core2Duo with 10.5.6 and all the updates. I had a Matshiuta DVD drive, which I took to Apple to have replaced because it would no longer read anything but Retail DVD, CD media (CDR's would read fine, DVD-/+ R however would not) It would read the discs for a second or two, then spit them out. Apple replaced the drive in September. Now, I have a HL-DT-ST DVDRW GSA-S10N DVD drive, which is a Hitachi/LG drive. Entirely different manufacturer... almost a year apart in manufacturing. and the SAME issue is happening. Only Retail DVD and any CD media (CDR's read fine) will read. Everything else it tries to read, but spits out. Here's the system profile dump on my DVD drive. The only kind of DVD media I use is Taiyo Yuden DVD-R media. CD's only get used when the machine is on a flat surface, never picked up while media is reading... etc. I've used the new one (HL-DT-ST) *maybe* 10 times if that. What the hell is going on?! There has to be something that is leading to this issue. 2 DVD drives from 2 different manufacturers and 2 different periods of times... the odds of them both failing in the same way are not good. Does anyone have any suggestions on what I might try to fix this?
