DriveScrubber’s Free Space Wipe feature has been removed due to critical data safety concerns. These new problems are caused by a significant change by Microsoft to the Windows file system for all Windows versions from XP through 10. It was discovered that using the Free Space Wipe feature can now also occasionally wipe valuable data, including critical portions of the Windows OS itself.
Microsoft has updated the file system maintenance behavior in way that causes existing Free Space disk sectors to now frequently have valuable data in them. In other words, Windows is now dynamically and unpredictably shifting the location of data across the disk platter, making it unreliable to pinpoint where the free space actually is. Due to this change in Windows, Microsoft warns that there is no safe method for wiping just free space.
