you could make a boot floppy as well as use a live cd for this as it doesnt mount your hd and therefore can check it but just a question what file system are you using?

you need to have some linux that boot's from cd...
if you are using distro which had console install(like Gentoo and Slackware) boot it and do 'fsck /dev/hdaX'. If you are using something like Red Hat, Mandrake or SuSE boot their cd, wait till graphical instalation starts then press "Ctrl+Alt+F2/F3" it should give you access to console. Then just do 'fsck /dev/hdaX'

This is because you can't fsck an partition that is mounted, and even in linux S, the / is mounted. Follow CatSC's advice...
