I have my macbook and i wanna install both linux, osx 10.5 and XP on it, and then i feel that 80 GB isnt quite enough. I mean its enough to have it, but in searching more like 330 GB so i can have quite a good bunch of space in all systems. So i say, can i have 2 harddisks in a macbook? Im thinking about keeping my 80 GB and then also putting in another 250 GB. Is that possible?
