Just run fsck and follow the prompts. Do this in single user mode. I
assume that this not a file system with the O/S itself on it (eg it is
not / or /usr or /var, etc.) If it ends up asking to do massive
repairs, it might be that the file system is totally fubar'ed, in which
case, doing a mkfs and doing a complete restore might be what you have
to do. Be prepaired for this case. It is good that you have a good
backup!
