Wonderful Self-Powered External Hard Drives

Sometimes technology is wonderful. As one who has suffered over the years with trying to store data and programs on floppies, recordable Cd's & DVDs that never quite had enough space or corrupted, the advent of the USB connectable external hard drive has been a blessing. But now they've gone one better with USB-powered Hard Drives, these make it a breeze to backup data or transfer files. I bought this one (see below) from Amazon . It is so light that when it was delivered I thought the box was empty!!
