Re: How do you retrieve files, documents from a laptop HD.
Most of the USB drive enclosures (and that's the terminology you'd use to Google or purchase) get their power from the USB bus. Many, in fact, have two USB cables -- the data are only transferred on one of the cables, but the second is used to make sure that there is enough 5-volt current to spin the drive. You may find an enclosure that uses an external "wall wart" to supply power, but the ones I've seen thus equipped are the more expensive variety (usually for 3.5" drives, which also need 12-volt power). Make sure the two USB cables are hooked to different buses -- most desktops use a different bus channel (with separate power buses) for the front and rear USB connectors.
