If all you want to do is fsck then have a look in your init.d scripts.
Some distro's allow you to request an fsck on boot by creating a file /forcefsck
(or equivalent).
ie.
	%# touch /forcefsck
	%# reboot

Most distros also default to use the 'max-mount-counts'  (or 'interval-between-checks')
property of ext[23] filesystems to trigger an fsck after so many reboots (remounts actually
but the fsck will only occur on a reboot).  It usually defaults to 20-30 reboots.
This can be a serious PITA if you switch a machine on to do a five minute job and it
decides now is the time to fsck that large partition you keep around.

Have fun,
