I usually "discover" that I am having data corruption when trying to 
update ports. A file that has a "Bad File Descriptor" refuses to let 
cvsup overwrite and/or remove itself. I've also had "make installworld" 
fail on me for the very same reason. A file in the base system would get 
corrupted and would prevent anything from overwriting itself. These 
problems would go away after a full system fsck, but the fsck would 
remove the damaged files completely, sometimes leaving the system in a 
severely broken state. And even if it did not, data corruption would 
happen again in 8-12 days.
