(1) Use tune2fs to set how often a full fsck is done, based on the
number of mounts or the amount of time since the last one.
(2) Convert your filesystems from ext2 to ext3, if your kernel supports
it (tune2fs -j).
(3) You can change the last field of the line in /etc/fstab to zero, so
the filesystem will not be checked at boot.
(4) You can run fsck on an unmounted filesystem or one that is mounted
read-only.
