I'm not sure if there is an external drive out there that can get power from USB. If there is, it might be a 2.5 inch drive (or smaller).Regarding TrueImage, I've used it for over a year. It's great. I backup up everything to a second hard disk weekly. I copy this backup to an external drive (USB enclosure + power brick) monthly and keep this offsite.

I have an enclosure that fits a 3.5 inch drive. So I can put a monster 750 gig drive in there if I need to (its 250 right now). There are all kinds of 3.5 inch enclosures floating around out there. You buy the enclosure, then buy a drive. It goes in the enclosure and you're done. I have found this to be cheaper, and you can spec your drive more exactly (get a fast drive) than if you buy one with the drive already built in.
