Or use a liveCD; there are lots now dedicated to recovery and repair and
they all have a terminal and fsck. The advantage is that if you find a
problem you're already in an environment set up to do the r & r.
On my most valuable desktop I actually have an 8 GiB partition with
Knoppix which I start from the DVD with the fromhd=/dev/sdx cheatcode.
There's also a persistance file, so I'm almost instantly in a
comfortable, familiar environment with all the other partitions
unmounted but available. I boot it once a month or so and fsck.extn
-vfc everything. I'm old enough to remember when Knoppix was the *only*
liveCD; I still think it's the best general purpose one because of its
superior hardware detection.
