Hello all, I want an external hard-drive to move my massive amount iTunes files over to. It's taking up so much space on my iMac to the point that I'm being told by my all-knowing machine that I need to free up 3.2GB before I can update software. I'm in the market for something of a minimum size of 1TB, preferably no more than £150, £180. Yes, I'm British. All help and advice gratefully received. Cheers.
