3. Data erasure - Wikipedia

   en.wikipedia.org/wiki/Data_erasure

   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 ...

4. Data sanitization - Wikipedia

   en.wikipedia.org/wiki/Data_sanitization

   NVMe defines formatting with secure erase. [18] 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]

   The Gutmann method, Quick Erase, DoD Short (3 passes), and DOD 5220.22-M (7 passes) are also included as options to handle data remanence. 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 ...

   The table below identifies each notable operating system and the first version supporting the command. Additionally, older solid-state drives designed before the addition of the TRIM command to the ATA standard will need firmware updates, otherwise the new command will be ignored. However, not every drive can be upgraded to support trimming.

   It supports a variety of data destruction standards, including British HMG IS5 (Infosec Standard 5), American DoD 5220.22-M, and the Gutmann method which features a 35-pass overwrite. [ 7 ] The tool has been recommended in TechAdvisor , [ 8 ] The Guardian , [ 3 ] and PC World , [ 9 ] and is a tool suggested by the United States government ...

8. Disk formatting - Wikipedia

   en.wikipedia.org/wiki/Disk_formatting

   A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...

9. Data remanence - Wikipedia

   en.wikipedia.org/wiki/Data_remanence

   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 ...
