as the macbook harddrive is in a user accessable location can i change it without voiding the warrenty on the macbook? Ive got my macbook dual booting OSx and XP and im running a little short on space on the stock 60gb. i wanted to pop a 120 in, any 2.5" sata drive should work right? Also is it possible to copy my existing harddrive and resize both the xp/osx partitions? I have a 60gb 2.5" drive in a usb caddy can i image the internal drive to this then restore it back to the new drive. Reason is beucase ive just got everything setup how i want it.
