but it works doesn't it

this is because you mounted your disk more than 28 times (or something like that). Linux recommends doing a filesystem check.

You can do this by running the command e2fsck /dev/hda1

Alternatively, you can use tune2fs to disable / alter the time between checks.

see man 8 tune2fs for more info
