My understanding is you can't run fsck on a mounted partition.

My approach to this would be to boot Linux from a live CD / USB Ubuntu
media. This should mean that /dev/sda6 will mounted at that time and you
should be able to fsck /dev/sda6

What do other people think?

Also, there is a package called smartmontools that contains the smartctl
program that can be used to monitor the health of hard drives. If that is
installed then "man smartctl" should give you sufficient information.
