Yes, gparted can do that; copy partitions from drive to drive. Very. very
handy program, especially when it exists on a LiveCD so that you can
work with unmounted filesystems. I use the Ubunto LiveCD to do this
as it does not exist on Fedora's LiveCD, but no big deal I think. The nice
thing is that it allows you to resize/move partitions around while you are
reorganizing a new drive.
Question: Could I simply use dd to copy over the MBR from drive to drive
or is it too risky?
