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]
However, certain tools can be used to modify the HPA or DCO. The system uses the IDENTIFY_DEVICE command to determine the supported features of a given hard drive, but the DCO can report to this command that supported features are nonexistent or that the drive is smaller than it actually is.
In 2008, Hard Disk Sentinel DOS version was released in different formats on bootable pen drive, CD, floppy. Usable when no operating system installed (or if the system is not bootable otherwise) to detect and display temperature, health status of IDE, SATA hard disk drives and with limited AHCI controller support.
The Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) was created to monitor and detect signs of a failing hard drive automatically.

Note: On Windows, the volume serial number is displayed only for disks formatted with MS-DOS version 4.0 or later. OS/2 allows the user to specify more than one drive. The vol command displays the volume labels ...
The exact behaviors of various fsck implementations vary, but they typically follow a common order of internal operations and provide a common command-line interface to the user. On modern systems, fsck simply detects the type of filesystem and calls the specialized fsck. type (Linux) or fsck_ type (BSD, macOS) program for each type.
A trim command (known as TRIM in the ATA command set, and UNMAP in the SCSI command set) allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered to be "in use" and therefore can be erased internally.
The chkdsk command on Windows XP. CHKDSK can be run from DOS prompt, Windows Explorer, Windows Command Prompt, Windows PowerShell or Recovery Console. [10] On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk).
