UK suggestions please for reliable 1TB Portable Firewire External Harddrive please! I made a thread before but it got cluttered up with a few desktop options, US only options etc. I need an external harddrive which is portable, doesn't require an external power source, works from the firewire port and is preferably 1TB so i can partition 500GB for data, 500GB for time machine. My harddrive in my MBP will be 500GB. Do I need more space for time machine or a separate drive even? Suggestions? Thank you!
