hdparm is a command line program for Linux to set and view ATA hard disk drive hardware parameters and test performance. [2][3] It can set parameters such as drive caches, sleep mode, power management, acoustic management, and DMA settings. GParted [citation needed] and Parted Magic both include hdparm. [4]
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
Command-line interface. A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command-lines.

MS-DOS command prompt with drive letter C as part of the current working directory. In computer data storage, drive letter assignment is the process of assigning alphabetical identifiers to volumes. Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter ...

In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost ...
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. However, certain tools can be used to modify the HPA or DCO. The system uses the IDENTIFY_DEVICE command ...
label (command) In computing, label is a command included with some operating systems (e.g., DOS, [1] IBM OS/2, [2] Microsoft Windows [3] and ReactOS [4]). It is used to create, change, or delete a volume label on a logical drive, such as a hard disk partition or a floppy disk. Used without parameters, label changes the current volume label or ...
