Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk, memory card or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems .
Device configuration overlay (DCO) is a hidden area on many of today's hard disk drives (HDDs). Usually when information is stored in either the DCO or host protected area (HPA), it is not accessible by the BIOS (or UEFI), OS, or the user.
In computing, format is a command-line utility that carries out disk formatting. It is a component of various operating systems , including 86-DOS , MS-DOS , IBM PC DOS and OS/2 , Microsoft Windows and ReactOS .
The functions currently supported by Disk Utility include: [1] Creation, conversion, backup, compression, and encryption of logical volume images from a wide range of formats read by Disk Utility to .dmg or, for CD/DVD images, .cdr; Mounting, unmounting and ejecting disk volumes (including both hard disks, removable media, and disk volume images)
The definition of "high-level formatting" given by vocabulary.com does not say anything about disks/drives or partitions within a disk/drive - which is a good thing, as there exists an object (/tmp/fatimage.dmg on my machine) that is not a disk/drive and is not a partition within a disk/drive but nevertheless contains a root directory and a ...
The Differencing hard disk image format allows the concept of Undo Changes: when enabled, all changes to a hard drive contained within a VHD (the parent image) are stored in a separate file (the child image). Options are available to undo the changes to the VHD, or to merge them permanently into the VHD.
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.

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]
