Yes, I know I could search for other threads on this basic subject, but I would like my specific questions answered. Anyway, I am picking up one of the new MBPs in a week or so. I need an external harddrive to go with it. I am looking at 320-500 GB, and a $150 to $220ish price range. I need to be able to make 2 partitions, a small one to back up the MBP and a big one for various multimedia (music, movies, documents, etc.). The ability to use it on both Mac OS X and Windows XP would be a plus (can they all do this?). Right now, I am thinking I will either get: 1. LaCie F.A. Porsche Design 320 GB http://www.futureshop.ca/catalog/pr...angid=EN&sku_id=0665000FS10085214&catid=23795 or 2. Seagate Free Agent Pro 320 GB http://www.futureshop.ca/catalog/proddetail.asp?logon=L&langid=EN&sku_id=0665000FS10087565&catid= or 3. Seagate Free Agent Desktop 320 GB http://www.futureshop.ca/catalog/proddetail.asp?logon=L&langid=EN&sku_id=0665000FS10087572&catid= Which of these do you recommend? I personally don't want to go with a My Book from WD because I have heard a lot of bad things about them. Also, can any of these be run through a firewire 800 connection? Is it worth the extra money to get one of the Seagates? And on top of that, is it worth the $20 to get the Pro edition as opposed to the Desktop edition? Thanks for the help.
