   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 ...

6. Trim (computing) - Wikipedia

   en.wikipedia.org/wiki/Trim_(computing)

   Regardless of operating system, the drive can detect when the computer writes all zeros to a block, and de-allocate (trim) that block instead of recording the block of zeros. If reading a de-allocated block always returns zeros, this shortcut is transparent to the user, except for faster writing (and reading) of all-zero blocks, in addition to ...

   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]

9. 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 ...
