Hi, I recently got a powerbook g4 titanium, it is the 1GHz DVI one ("Antimony"). My DVD drive is not able to read disks and sometimes doesn't eject disks properly. Now, the issue is, I live in the UK, and I can only get the part I need from the USA. Will a US DVD drive work in my British machine? well, obviously, it will work, but isn't there any region lock stuff going on? I need this drive to work so I can install Mac OS 9 or 10 on to the hard drive, any other methods (attempting to boot from a USB DVD burner) have failed and this is the only PPC mac I own. I own two other intel macs. One is a mid 2011 Mac Mini the other is a white unibody 13" macbook from mid 2010. anything I can do? thanks. note; It does spin CDs and DVDs, but will try and read them, you can hear the motor quite well. I don't know if that is normal for these, but I learned after a bit of research that the motors in the combo drives are common to fail. I cannot hear it reading the disk, either. my hard drive is currently dead inside the machine (I went to test it, but the caddy at work killed it) and I want to get the DVD drive working before I replace the HDD. tl;dr: will a US combo drive read dvds from the UK, incl. install disks? EDIT: I have replaced the HDD with a 250GB samsung PATA drive. I have partitioned it for five OSes.
