go you have a mac or pc?
i have a mac & a lot of my stuff is tored on a lacie... (music, video files, etc) becuase i ran out of space on my hd.
they're not hard to use. you just plug it in to the right port (look @ the instructions) and then you will see the external as an icon on your desktop, & you can just drag files into it. no problems. just make sure to eject it before you unplug it.
