ok. my desktop is rapidly running out of space, i have a 250GB HD and a 500GB HD. the 250 has XP and partitions for games and the 500 has Vista and a partition for Music/Movies and programs that i have stored. Im planning on removing XP and going with solid vista but would still like some extra room for storing my movies, TV shows, and music that i have on the drives. i figured i could either remove the 250HD and install a 1TB one or get a 1TB external drive that i can use to move music/movies between my Vista desktop and my MacBook. And also use the 1TB drive as a backup drive for use with time machine. I would buy Time capsule, as i really want it, but as a student living with 5 other students i really cant justify the purchase as we already have a perfectly good router. (one question is can timecapsule be used to back up a windows desktop? or just mac?). Also if i was to have a external drive would i be able to put my music on it and which ever iTunes i acces the music thru (windows or mac) it would detect my music/play count and playlists automatically? Thanks.
