Well it has taken me almost 5 days to upgrade my EeePC disk from the 80Gb stock issue to a 320Gb drive. The main problem is that most of the disk cloning software just absolutely sucks and failed in one way or another when I tried to use it.
However xxClone came through, worked superbly and was extremely easy to use. I now have 268Gb for music/data, WooHoo.
