This is a super basic program that does one thing very well. It will restart, defrag, and then shutdown your computer. I have been using it for two week now without a problem. It only has two options. One hard drive (which you can select ) or all hard drives. I start it when I need to defrag and am going to shut down my computer. I have been using it daily, sometime more, to test drive it. So far so good.
Good product. Freeware. It is now on my recommended utilities list.Speedefrag 2.1
