Thanks. The drive has a Firewire 400 port and a USB 2 port. The computer has a thunderbolt port and I connect the drive to my computer with a 400 to 800 firewire adapter connected to a firewire 800 to Thunderbolt adapter.
Do those adapters slow transfer speeds? Would I be better off using the drives USB 2.0 port to connect it to my computer?
