O&O DiskStat is a high-performance utility for analyzing used disk space on storage volumes. Systems find their performance adversely affected by the amount of information stored and the burden this places upon them, so much so that a worthwhile backup is almost impossible.
Available now in stores is O&O DiskImage 3 Professional Edition. A new time-scheduling feature will allow you to perform automatic data imaging on a regular basis. Drivers that aren't available by default, can be load with the unique O&O DriverLoader.
