I currently have a mbp and I'm running bootcamp on it. 160 gig on mac hd and 40 gigs on windows hd. I'm running out of memory and considering getting an external hard drive. Would I be able to back up both my mac and windows partition on the same external hd? Also Is it possible to install programs on the external hd (For ex. installing games on external hd and running it from the external?) Also my itunes library is on my mac hd. How would i be able to play my itunes library while running bootcamp? Thanks.
