Windows chkdsk /f equivalent in Linux
Checks and repairs a filesystem while unmounted.
chkdsk /f
sudo fsck -f /dev/sdXn
sudo fsck -f /dev/sdXn
sudo fsck -f /dev/sdXn
Overview
What this command does
On Windows, "chkdsk /f" is used to force filesystem check. On Linux, the closest practical mapping shown here is "sudo fsck -f /dev/sdXn". Checks and repairs a filesystem while unmounted. This reference is grouped under System & Storage → Filesystems.
Windows → Linux context
What changes when you use this on Linux?
Equivalent task, different tool
Windows chkdsk /f maps to sudo fsck -f /dev/sdXn for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Portable across the compared distros
The Debian/Ubuntu, Fedora and Arch rows use the same command in this mapping. Package availability or defaults can still vary, so check the installed tool version when an option behaves differently.
Elevated privilege appears in this workflow
At least one example uses sudo. Confirm the target path, device, service or package before running the elevated form; do not add sudo simply to bypass an unexplained permission error.
For the broader concept behind this mapping, read Linux disks, storage and mounts.

Distro differences
Debian/Ubuntu vs Fedora vs Arch
Debian/Ubuntu, Fedora and Arch all use "sudo fsck -f /dev/sdXn" for this mapping. The command syntax shown here is portable across the three rows, although installed versions and system defaults can still vary.
