I'm in the market for an external hard drive, had a friend recently tell me about one that exploded but didn't tell me the brand. What external hard drive do I want? 500 gb USB for New Airport Extreme Possible fan cooled Been looking at 500 gb WD My Book Pro 800/400/USB also at OWC Clasic Pro 500 gb 800/400/USB Suggest others????? Iomega? G-Drive? LaCie? But seriously, I've tried to get feedback on this before and had little success with forums. So, If I could get your quick 2 cents on this I would appreciate it.
