This is on a PowerBook G4 1.33ghz. I just maxed the RAM today to 2GB and plan to upgrade the HDD to one I already bought (250GB) and Leopard. I have encountered a few problems. 1. I didn't bring the Leopard DVD (original) as I didn't want to carry it with me to in my carry-on luggage (the laptop is with my fiancee in Japan). I made an image of it and have it on my iPod. The iPod is USB connected (not firewire). I didn't know I had to restart to install Leopard and now it doesn't work! 2. Should I buy an external case for the new HDD and clone the contents of my existing drive to that? It would be easiest to do that, but I'd be spending money for an external case and won't solve the problem of installing Leopard? I don't know what to do. I want to avoid buying an external HDD case. Anyway to do this efficiently? Thanks.
