i've had my computer almost a year and a half now. i've reformatted twice since i've had it, and have never ran defrag that i can remember. that's bad, i know. lately my computer has been running rather slowly and i'm assuming that defrag needs to be ran. the problem is i run defrag over night and i check it the next day and it hasn't moved from 0%. that can't be right can it? 0%? i'd think it should atleast be past 0% after running for 9 hours. i know defrag sometimes takes a while and i know it'd probably take a long time to defrag my computer since it's pretty much never been defragged, but still being on 0% after 9 hours?? can anyone help me with this? let me know what could be wrong? thanks.
