ScanDefrag is a small windows application that configures Microsoft's or Norton's disk utilities as part of the next Windows' startup process. This can result in less restarts and cleaner runs of these programs. Please read the readme file for more information and features available.

This is so important that I added this program even though it is not freeware. It keeps your hard drives in good condition, and if they crash, picks up the pieces and restores the hardware. I used Spinrite 2 in 1991, it disappeared for a while, and now it's back. This program must be run from a DOS prompt, not a DOS window.
