Any clues why Disk Defrag won't work? 70% free space on HDD. DCOM Service is set. Hasn't worked for a while, been using Defraggler. I'd like to get Win 7 working again (back-ground defrag). Tried Auslogics, and it took too long. The problem I'm having, is that the best defrag I can get is 37%! It used to be that after a defrag, I would be left with 2 - 3 % fragmentation. Any ideas, or should I even worry about it?
