going to give this a go today, I have used disk keeper for years, but recently it just doesnt seem to be doing its job very well.
every time I analyse my boot drive after a reboot it shows it as a right old mess, defragmented bits everywhere. I defrag, all look well, then rebbot and anaylse and its screwed again. Also taking an age to boot and its a speedy raptor too so no excuse really.
will give this a whirl and see how it goes
