I just bought recently Diskeeper 2008 and every time I try and do a manual defrag, it takes forever to get anywhere. For instance, It ran for 6 days straight and was only at 84%. It didn't finish because I stopped it. And I have trialed a few other programs and it still won't defrag my computer. What the heck is going on? Windows Vista Home Premium 32 100 gigs used on a 500 gig HD. BTW, I have contacted Diskeeper support and they haven't helped me at all.
