Filesystem Check (fsck)

Filesystem Check (fsck) is a utility that examines a computer's storage drives for errors or inconsistencies, ensuring data is correctly organized and accessible. When the system detects potential problems—like corrupted files or misplaced data—fsck repairs these issues to prevent data loss or system crashes. It’s similar to a mechanic inspecting and fixing a car to keep it running smoothly. Usually run automatically during startup or manually by the user, fsck maintains the integrity of the storage device, helping your computer function reliably over time.
