Hello. I have an interesting setup and I need some help with Time Machine. I currently have an internal 160HD and two 250GB external drives. I am looking for a drive that can backup these three drives. I am thinking of 2 500gb drives but I am not sure if I can make Leopard see the 2 drives as 1, or else (I THINK) I will have to select one 500gb drive to backup my two 250GB (which will fill up fast) and a 500GB drive for my 160GB internal. I can always buy a 1TB, but it is more expensive than 2 500gb drives (ridiculous). I need a full briefing because I know nothing about multiple-drive Time Machine backups. Any information is useful. Thanks.
