I just ordered a 1 terabyte WD external drive, and I'm planning on creating one partition for music/movie storage, and a second smaller partition for a superduper clone. So my first question is, what format should each partition be in? I'd like the movies/music partition to be Windows compatible...will choosing FAT32 make any difference in my use of this partition when used with my OSX machine, and what benefits would I see by using Extended Journaled instead? Then, what format do I want the Superduper backup partition to be? Finally, when I initially format and partition the external drive, is there anything I should do to prepare it first, or just go right ahead, divide it in two (approx. 650gigs for music/movies, the rest for superduper) and then format each partition on its own into the formats they need to be in? Thanks! Also, do I use GUID partition format? As you can tell, I'm a bit confused about some of this.
