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).
It is possible to use the WDTLER.EXE utility directly with the -r# -w# parameters for a custom timeout. Western Digital claims that using the WDTLER.EXE utility on newer drives can damage the firmware and make the disk unusable. The utility is no longer available from Western Digital, and new drives will not be able to have the TLER setting ...
The Recovery Console has a simple command-line interpreter (or CLI). Many of the available commands closely resemble the commands that are normally available in cmd.exe, namely attrib, copy, del, and so forth. From the Recovery Console an administrator can: create and remove directories, and copy, erase, display, and rename files
CHKDSK verifies a storage volume (for example, a hard disk, disk partition or floppy disk) for file system integrity. The command has the ability to fix errors on a volume and recover information from defective disk sectors of a volume. The command is available in MS-DOS versions 1 and later. [1]
Starting with version 4.0, the alternative command line processors 4DOS and NDOS supported /F and the corresponding CritFail=Yes directive in 4DOS.INI/NDOS.INI as well. The option was also supported by the COMMAND.COM of PTS-DOS 6.51 and S/DOS 1.0, as well as by DR-DOS 7.02 and higher.

An early hard disk monitoring technology was introduced by IBM in 1992 in its IBM 9337 Disk Arrays for AS/400 servers using IBM 0662 SCSI-2 disk drives. [11] Later it was named Predictive Failure Analysis (PFA) technology. It was measuring several key device health parameters and evaluating them within the drive firmware.
