Formatting a disk for use by an operating system and its applications typically involves three different processes. [e]Low-level formatting (i.e., closest to the hardware) marks the surfaces of the disks with markers indicating the start of a recording block (typically today called sector markers) and other information like block CRC to be used later, in normal operations, by the disk ...
According to the University of California, San Diego Center for Magnetic Recording Research's (now its Center for Memory and Recording Research) "Tutorial on Disk Drive Data Sanitization" (p. 8): "Secure erase does a single on-track erasure of the data on the disk drive. The U.S. National Security Agency published an Information Assurance ...

Restoring the software of an electronic device to its original state For the Tilian Pearson album, see Factory Reset (album). A factory reset, also known as hard reset or master reset, is a software restore of an electronic device to its original system state by erasing all data ...
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.
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 ...
Typing "format" with no parameters in MS-DOS 3.2 or earlier would automatically, without prompting the user, format the current drive; however in MS-DOS 3.3 and later it would simply produce the error: "required parameter missing". [citation needed]
Trim was introduced soon after SSDs were introduced. Because low-level operation of SSDs differs significantly from hard drives, the conventional manner in which operating systems handle storage operations—such as deletions and formatting—resulted in unanticipated progressive performance degradation of write operations on SSDs.
