hi
its quite possible that the 203 days is correct and your system has a very long scan delay.
I have a ext3 system and mine is set to check after 30 cold boots or every 7 days....which suits me.
more mission critical people may prefer shorter delays.
2) assuming you have ext2 or 3 you can use a live cd to change your scan delays. ...target partition is left unmounted
man tune2fs ...will give you the options but I think you may like to look at example
tune2fs -c 30 -i 7 d /dev/sda1
3) while in live mode force a check now...again I assume you are ext2/3
Code:
su
e2fsck -f /dev/sda1
man e2fsck will give you options but I like -f first and follow the prompts
