I assume you are using Windows XP.
(if you have Vista the built in backup options are good (something had to be))
VHG is correct .. no 2 machines are the same ... but the layout is generally similar (if you'd changed system folders - you wouldn't be posting here ;-)
The new external drive will look just like another (local) hard disc so .....
the only way of identifying it in my computer is .... it's the one that wasn't there before! .... or if you unplug it (with my computer open) it will be the one that isn't there now!
ok?
If you are only interested in moving data
(and haven't scattered file everywhere)... all you need to do is to copy the contents of "My Documents" to your new drive.
and in future save any new files there as well
If you actually intend to use the disc for backups (a better option)
You can either do this manually (as above) ... or use the backup tools provided with XP to include favourites and other data - see

If this seems too complicated but sticking with microsoft - you could download the free sync toy
http://www.microsoft.com/windowsxp/using/digit alphotography/prophoto/synctoy.mspx - which is also a good simple option
if you also need virus protection Norton 360 is a good multi purpose allrounder
if you have a little money to spare
acronis true image 10 home
or
norton backup and restore
are both good value (and pretty reliable)
or google something like "free backup tools" and see what sounds good.
