Save your hard drive and your screen

Defragmenting your hard drive is a pain. Often the need for a defrag coincides with the need for system performance. We defrag when we notice that our computers are working slowly, and we usually notice a slow-down precisely when we are wanting our computers to work quickly. Defragging at such a crucial time compounds the problem. It can take multiple hours to cleanup a large hard drive. It was in such a defrag-induced downtime that the concept of hsDefragSaver was hit on. Why not have your computer defrag BEFORE a performance problem occurs? Better yet, why not defrag when the computer is idle? hsDefragSaver does precisely this. It is a screen saver and defragger combination, and it defrags your hard drive BEFORE you notice the need for it.
