I am sure someone has posted answer's to this question, so if you could just point me in the right direction it would be appreciated. My girlfriends Titanium PB, 1ghz is in desperate need of a clean install. I bought her OS X 10.4 today, and I want to back everything up and do a clean install of 10.4 rather than just updating her current set-up. Is there a way to create a clone of her current set-up (similar to Norton Ghost on the PC) in case I screw this up? What is the best way to store it, DVD's or can I copy it to a networked PC with an extra drive in it? When I do a clean install on my PC, I keep two drives in it. I clone eveything to one drive, do a clean install on the other. Boot from the new OS and then after reinstalling the software I just drag over any current files. When I'm sure I've copied everything I needed, I just wipe the old drive and use it as back up. I would like to do something similar to the PB. I was also thinking of buying a 5400rpm internal drive to replace the 4200rpm that is in it now. I could use the old drive in an external firewire enclosure, but I was hoping to defer that expense until later if at all possible. Thanks for the input. On a side note, how much RAM is recommended for the PB running 10.4?
