Look for the thread "running e2fsck pre-boot" on this list.

Willie Wong had the answer: tune2fs, not e2fsck.

$man tune2fs
...
It is strongly recommended that  either  -c  (mount-count-depen-
              dent)  or -i (time-dependent) checking be enabled to force peri-
              odic full e2fsck(8) checking of the filesystem.  Failure  to  do
              so  may lead to filesystem corruption (due to bad disks, cables,
              memory, or kernel bugs) going unnoticed, ultimately resulting in
              data loss or corruption.

 I ran it before on my SSD and it worked like a charm. But I neglected
to run it on the
SD card that holds /home and /var on my eee. Now it is starting to
display the same symptons. Yes I know, ext2 is rather retro, but I was
persuaded to use it by reading the forums and now it's a lot simpler
just to run tune2fs rather thman scrap the system and start again.

I know you  can convert an ext3 filesystem to ext4. Can you not do the  
same ext2 -> ext3?

Stroller.

Yes, with the -j flag to tune2fs.

And it doesn't destroy the files? If so, that's good news.

And iirc you can got ext3 -> ext2.  The same does not hold true for
ext4 -> ext3.

The man page says you can even do it to a mounted filesystem, but I'd
be more comfortable running tune2fs -j from a live CD or similar.

I haven't actually done this since ext3 became the standard many years
ago, but I'm pretty sure I converted unmounted partitions.

YMMV, naturally, and you might want to sacrifice a live chicken in front
of the computer before starting.  Couldn't hurt.
