It helps you to delete your sensitive data completely and permanently by overwriting. Please read below how it works …….
Explanation about the working of Eraser:
When we delete any file, the OS of our PC/Laptop does not really erase the data from the secondary storage; but, actually, it removes the exact reference (Reference means address of location where the data is actually stored) from the file system table, after which the data cannot be searched from the searching algorithms present in the system. And also it will show the memory space as free memory where previously our sensitive files resides. The system control unit update their file system table with that memory location as empty for upcoming data uploads, once a new data file comes, system provide the same location to this and save the new data onto the same locations, but, even after this overwrite, it may be possible to recover the data by study of the magnetic field patterns on the same hard-disk drive. The Eraser software do a unique step to safely remove all the stray marks of the data by overwriting preconfigured data again and again over the same location which is relatively matches the magnetic field patterns of your data. Hence, it could not be recovered by any way in future as it is became unambiguous for the deleted data. Currently, Eraser is supporting Microsoft Windows XP (with Service Pack 3), Windows Server 2003 (with Service Pack 2), Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2.
