To change disk check on bootup

issue the following command:

tune2fs -c or -i

to override default settings

for example - as root:

tune2fs -c 100 /dev/hda3
tune2fs -c 100 /dev/hda1 (100 mounts then check)

TO DETERMINE WHEN THE HDD WAS LAST CHECKED

tune2fs -l /dev/hda1
and look for Last checked:
