I want to buy an external hard drive, and I was going to buy one of 2 Western Digital externals until I started reading reviews and talking to friends, and I was advised not to buy a Western Digital drive. So, please help me find a good external drive. I want: 1TB preferred, but 750GB should be enough, 500GB is questionable. I want: Firewire 800, but USB 2.0 is OK, but Firewire 800 is greatly preferred. And all for under $175 or so.
