I am looking to get a Lacie d2 Triple interface external hard drive. do you know if i can hook up 2 computers (iMac and MBP) one on Firewire 400 and one on Firewire 800 at the same time? Do you know the cheapest place to get one in uk? I think i might be able to get away with a 160gb, but half tempted to pay that little bit extra for a 250 gb Bit of background I backup my powermac on an 80gb drive, i now have a iMac and MBP, i want to backup both (around 80gb each) so 160gb will be enough, but 250gb will allow for future use. I want to have the iMac and MBP connected at the same time so i can get automator back them up each night onto the drive. I know i could use a network drive but that would be a little slow unless i got a gigabit ethernet hard drive which i guess is expensive, thats why i wanna do the MBP with firewire 800 and the iMac with firewire 400.
