Query: Doesn't do the job

The Aegis 160 GB Firewire portable drive is a real disappointment. The biggest problem is that in most cases, it just doesn't work. On three of four computers that I used it on, it isn't recognized, doesn't power up, and is basically useless.On the one computer where it worked, it did the job, but not noticeably faster than a USB2 unit of the same size.Since it is supposed to be portable, not working on 75% of the machines on which I tested it proved to be less than adequate to the task. My recommendation is to buy a USB2 unit, instead.Because it is, indeed small and external, and works, I did not give it a single star, but two.
