Try reading all the files on the drive, something like

See if any files error out.

Boot to a single-user mode and see if /etc/passwd and /etc/master.passwd
are ok. If so, regenerate the databases (easiest way is to run vipw).

This doesn't necessarily mean there's an error. If you filled the file
system past its reserved space limit, it's normal to get negative
available bytes and over 100% usage. See also if you have a /lost+found
directory.

It is possible, with care, to reinstall the system from the CD media,
and keep all user settings. /usr/local/* will not be touched in any case
when performing an upgrade.
