This sounds a LOT like your disk is going bad.  Having e2fsck fix problems
like this, then immediately getting errors again is something I've seen
in the past and it turned out that the disk was flaky.  Try running
"badblocks" on the disk in non-destructive write mode and see what it finds.
I'd strongly recommend a backup at this point if you don't already have it.
