General

1. Check /etc/fstab; the last column for the FSes you want to check must not be 0 (requirement not confirmed but does no harm).
2. Ensure that /etc/default/rcS has FSCKFIX set to yes (requirement not confirmed but does no harm).

Use tune2fs to:

1. Ensure the max_mounts_count is >0 (option -c to set)
2. Ensure the number of mounts since the last check is greater than max_mounts_count (option -C to set)
