Summary: This thing broke down on me, believe it or not, three times and I'm on my fourth one. I'm glad they replaced it, but the last time they gave me a USB hardrive instead of a firewire. It never lasted me for over a year. And guess what? This fourth one just messed up.
Summary: I was impressed with the online reviews and the specifications of this handy external drive. However, it failed (as in very dead) during my first use, backing up my MacBook. Two different customer service reps were very rude as we were trying to diagnose the fault. And it was a toll call.
