Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process. By overwriting the data on ...
HDDerase is a freeware utility that securely erases data on hard drives using the Secure Erase unit command built into the firmware of Parallel ATA and Serial ATA drives manufactured after 2001. [1] HDDerase was developed by the Center for Magnetic Recording Research at the University of California, San Diego. HDDerase is designed for command ...
Opal Storage Specification specifies a command set for self-encrypting drives and cryptographic erase, available in addition to command-set methods. The drive usually performs fast cryptographic erasure when data is encrypted, and a slower data erasure by overwriting otherwise. [18] SCSI allows for asking for a specific type of erasure. [17]
If available, the SATA secure erase command, issued through hdparm or a similar utility, may be helpful in this situation. Even for magnetic devices, SATA secure erase will be faster and more reliable than shredding. Physical destruction may be necessary to securely erase devices such as memory cards and unusable hard disks.

Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
DBAN can be booted from a CD, DVD, USB flash drive or diskless using a Preboot Execution Environment. It is based on Linux and supports PATA (IDE), SCSI and SATA hard drives. DBAN can be configured to automatically wipe every hard disk that it sees on a system or entire network of systems, making it very useful for unattended data destruction ...
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.
