Hi:

File system Check or sometimes pronouned 'f-sick'. It is used to check to integrity of filesystems before mounting. Normally, fsck is run automatically at boot if the system detects that a filesystem was not unmounted cleanly. e.g. after a crash.

Man fsck_vxfs or fsck_hfs for details.

Basically it's a filesystem check utility or command if you will. If you have data corruption occur on your disk, it will continue to exist until you fixes it (ie. correct the database data files/index) by running fsck on the filesystem. Fsck will only detect/correct problems with the file system infrastructure, and not the contents of files - meaning data files (raw or file system files) will not be examined nor corrected by fsck.
