Software-based data erasure uses a disk accessible application to write a combination of ones, zeroes and any other alpha numeric character also known as the "mask" onto each hard disk drive sector. The level of security when using software data destruction tools is increased dramatically by pre-testing hard drives for sector abnormalities and ...
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.

[1] [2] A distributed file system is a protocol that provides file access between networked computers. A file system provides a data storage service that allows applications to share mass storage. Without a file system, applications could access the storage in incompatible ways that lead to resource contention, data corruption and data loss.
Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.
In October 2013, a Disk Cleanup Wizard addon was released that lets users delete outdated Windows updates on Windows 7 SP1, thus reducing the size of the WinSxS directory. This update backports some features found in Windows 8.
