In computing, CHKDSK (short for "check disk") is a system tool and command in DOS, Digital Research FlexOS, [ 1] IBM / Toshiba 4690 OS, [ 2] IBM OS/2, [ 3] Microsoft Windows and related operating systems. It verifies the file system integrity of a volume and attempts to fix logical file system errors. It is similar to the fsck command in Unix ...
Operating system. MS-DOS 6.2 and Windows 9x. Type. Utility software. License. Proprietary commercial software. Microsoft ScanDisk (also called ScanDisk) is a diagnostic utility program included in MS-DOS and Windows 9x. It checks and repairs file systems errors on a disk drive, while the system starts.
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]
Command Prompt, also known as cmd.exe or cmd, is the default command-line interpreter for the OS/2, [ 1] eComStation, ArcaOS, Microsoft Windows ( Windows NT family and Windows CE family ), and ReactOS [ 2] operating systems. On Windows CE .NET 4.2, [ 3] Windows CE 5.0 [ 4] and Windows Embedded CE 6.0 [ 5] it is referred to as the Command ...
In addition, the System File Checker utility ( sfc.exe) was reimplemented as a more robust command-line utility that integrated with WFP. Unlike the Windows 98 SFC utility, the new utility forces a scan of protected system files using Windows File Protection and allows the immediate silent restoration of system files from the DLLCache folder or ...
In CP/M, attempting to read a floppy disk drive with the door open would hang until a disk was inserted and the disk drive door was closed (very early disk hardware did not send any kind of signal until a disk was spinning, and a timeout to detect the lack of signal required too much code on these tiny systems). Many users of CP/M became ...
TestDisk can recover deleted files especially if the file was not fragmented and the clusters have not been reused. There are two file recovery mechanisms in the TestDisk package: [2] TestDisk proper uses knowledge of the filesystem structure to perform "undelete". PhotoRec is a "file carver". It does not need any knowledge of the file system ...
