Just some background - I have last year's 13" Macbook pro. It has a 2.26ghz Intel core 2 duo P7550 processor, 2gb of ram, and a 160gb hard drive. I have partitioned the hard drive into 130gb for my Mac OS, and a separate 32gb is partitioned for Windows, where I have Windows 7 Ultimate installed, and I run it using bootcamp. I have very little space left on my windows partition (~500mb), and it's started to run pretty slow, playing runescape and normal computer stuff. I'm wondering if hard drive space would affect this. If it does, (and even if it doesn't), I'm planning on buying an external hard drive. My main question is if I buy one hard drive, would it work for both my Mac OS and my Windows on the same computer, or would I need two separate ones? I'll mainly be putting music, movies and games on it. The last question (that I can think of) is can I install a pc game, for example Skyrim, when it comes out, on the external drive and play it? And is there a way to do this without needing the disk? I had a friend do something with Daemon tools and he put Oblivion on my computer so I don't need the disk. Or, should I just buy it on Steam? I've never used it. Sorry for the question barrage, but hope someone could help!
