<font color=blue>...I've been using Diskeeper for years (first ran into it on a VMS machine) and still think its one of the best.</font color=blue>
I never used that one, but when I was managing a big VMS system I used something similar.. made by Raxco. This was years ago, and I don't know if they even exist anymore, let alone have products for PC's. But yes, disk defragging is a good thing. What I loved about Raxco is that they had all kinds of dynamic tuning utilities.. things that would normally require manual analysis and fooling around and re-booting.. they could change on the fly as system loads dictated. I used everything they had, and never regretted it. I'll have to look into the Diskeeper products now that I'm just running PC's. Norton's leaves something to be desired, in my humble opinion.. but maybe I'm just not using it right.
