I just downloaded Defraggler today. My hard disc has not been defragged for a long time. The defrag app on my computer won't work on this mess. It gets to about 3%, then just kind of sits there. So, Defraggler for me! However, Defraggler aborts before it is done. I have not seen any sort of message as to why, it just says the app aborted. Last time, I was about 60% into it when it shut down. Any ideas anyone?
