You will still need a mains supply for your external hard drive.
Plug into mains, attach your usb cable and run as a normal hard drive.
In most cases you must install your drivers BEFORE you connect your drive, but with windows "vista" you may not have to.


Hope this helps:thumbsup:

Portable hard drives Ok heres a question for the people who know their stuff on computers.. at the moment i just have a shitty laptop with only 30GB space on and i want to buy a portable hard drive for it does anyone know how they work? Is it just as simple as dragging the files onto it or is it much more complicated? How many wires does it come with is it just the USB? Thanks :) Rating: 5
