This is usually what happens if you power off the machine without properly
shutting down the machine. fsck is analogous to scandisk in Windows.. If you
power off the machine without shutting down properly, Windows will run
scandisk the next time you boot up to correct filesystem errors.

Then answer yes to all questions.

That should do the trick. Usually, the machine will be able to run fsck by
itself and correct everything, but sometimes, as in this case you're
experiencing, fsck must be run manually.

Once you fix the filesystem, be sure that in the future you shut off the
machine all the way before you power down.
