Recently, I accidentally knocked the power swich on my 'puter just enough
for the machine to decide to reboot itself.  On the way back up, it made
me run fsck manually; fsck proceeded to "fix" things (the primary complaints
I seem to remember were two entries for single files and files not being
allocated the correct amount of space) and put close to 200 files in
/lost+found.  It's fairly difficult and/or time consuming to figure out
the old names of files in /lost+found (I think they were now given names
representing inode numbers) and where they used to live, so much so that
the best course of action for me was to either restore from a full backup
or reinstall from the original media.  While corruption in unix filesystems
may be rare, when it happens, it happens with spectacular glory.
