Hi, Does the USB port on the 360 give sufficient power to use an external 2.5inch laptop drive without additional psu. If so can anyone recommend an external 2.5 enclosure which is reliable etc. Oh and as an aside, is it possible to partition an external drive and have a FAT32 and a Mac format HFS+ partition. The idea being I can keep some HD movies on HFS partition and still be able to swap the drive around various PC's and use the FAT32 partition for other stuff. Cheers Martin.
