Hi guys. Im looking for 2TB External HDDs with two firewire ports so that I can create a daisy chain (seeing as iMacs only have 1 firewire port). I cant find drives with 2 firewire ports on the same HDD (not in UK stores anyway) which are higher than 2TB. The seagate go flex 3TB caught my eye but I dont think its Firewire component has two firewire slots. Anyone help me?
