Hi I just bought a PowerBook G4 Titanium 400Mhz from eBay. It all works fine, but the DVD drive is temperamental. The casing above the optical drive slot is cracked which means the casing is pushing down on the drive and has bent the chassis of the optical drive. It makes a scraping sound as it spins. I have managed to unbend it, but I think it is a temporary measure until it does it again. I need to find a new top casing for it. I want to upgrade the standard DVD-ROM drive with a superdrive or compatible drive. I checked Xlr8yourmac, and while their drive compatibility database lists drives that work in Titaniums, they don't narrow it down further. Anyone know or have a replacement drive or any help?
