Logical errors are contrasted with and usually less severe than hardware-level errors, which can not be fixed with CHKDSK and may instead require specialized data recovery software or hardware service or replacement.

CHKDSK (short for "check disk") is a shell command that verifies the data integrity of the file system on a volume (usually a partition) and attempts to fix logical errors software-level problems with a filesystem (or its metadata) as a result of prior software malfunction (e.g. crashes) or irregular use (e.g. hard resets). Logical errors are contrasted with and usually less severe than hardware-level errors, which can not be fixed with CHKDSK and may instead require specialized data recovery software or hardware service or replacement. Although the name ends with "DSK" as an abbreviation for "disk", the command supports storage media other than disk-based.
The command is available in DOS, Windows, FlexOS, 4690 OS, OS/2, DR DOS 6.0, and FreeDOS.
