The best way is to download a Live CD dedicated to recovery actions (for instance: http://www.sysresccd.org/Main_Page ) to boot, and to use tools as fsck.ext3, fsck, e2fsck (from e2fsprogs).

A fdisk -l with provides a clear description of the partitioning scheme.

Do not use the rescue CD for the system is mounted on /mnt/sysimage (partitions must stayed umounted for using e2fsprogs).

You really shouldn't run fsck on a mounted partition and there is a possibility of really borking it up. But if you boot to runlevel 1, then type unmount /dev/hdb3, then run fsck -f -p you'll be fine....
