Hi all - In my research for pen drives, I've also been looking at external USB hard drives, and am wondering what people have used successfully? Freecom seem to be the cheapest with a 250GB for £55; I take it that these drives require no mains power, so what are they like in terms of speed when transfering data? I've seen some drives advertised as TurboUSB, does this somehow mean they are faster drives? From some reviews I have read, is seems that some drives have to be formatter to NTFS, is this common, and how is a fat32 drive formatted so as to be NTFS? As ever, thanks for all help - Andy
