I created a vista partition on my MBP but would like to use an external hard drive to install games on it and play it from the external. could I do this and how do I go about doing this?
Some games are very picky about where they install themselves, and insist on being in your C: drive no matter what you do. If the game you're playing allows installing in a location besides the default, you shouldn't have to partition the external drive if it's already in a format Windows can read (NTFS, FAT32, etc.).
