Your choices are about right depending on how much information you keep
in /home.
On Gparted, it is a tool that doesn't get installed, you partition your
disk and either format
or not format, label the disk partitions which can make it easier to id
the partitions, I used
it because I didn't feel comfortable using the one on the install disk.
Now that I have been
through the install disk a couple of times I feel better using it. I
have an extra disk here
and will install it in a desk PC once I figure out how to install it on
the other bus and ID it.
and I will probably use Gparted to get the ID of the first disk, then
install the second and
run it again to ID the second, I haven't played with the buses before
and it sounds interesting.
