Hi, With my Macbook arriving tomorrow (I damn well hope - it's only 100 miles away now according to TNT), I'm wondering about upgrading the internal hard drive to a faster model with larger capacity. This would leave me with the stock 60GB drive, which I'd like to turn into a portable external backup disk. I would like some recommendations for external drive enclosures. They must obviously be 2.5" form factor, and must take a SATA drive (plus whatever else I need to consider - advice appreciated!). I'm very keen to find one which is powered entirely from a single USB/Firewire port. In my searches so far, I have found a few which need two USB connections - one for power, one for data. Perhaps this is the only option with a 2.5" enclosure and drive???. I am not interested in any enclosures which require a power brick. Suggestions welcome, particularly from retailers in the UK. Many thanks!
