> If I'm not mistaken the fsck command doesn't actually check the crc of the blocks.
> I just had a problem where a few blocks managed to get the size 0, fsck didn't report this but
> my hadoop programs started failing because some of the input data was corrupted.
> An option in the fsck program to actually check the crc would be nice, even though it would take a while to run.
