yes this is true, I forgot about it. a few years ago I was replacing
a drive on a SGI box which was running XFS. The system refused to run
fsck. It told me something like 'you don't need to fsck a xfs volume',
even though the disk was failing and data was being lost at the time.
perhaps this is why reiserfs does the same, it's nice to be able to
mark blocks as bad, but whenever I see bad blocks, I get ready for
an RMA, because most likely when bad blocks start showing up on the
filesystem itself, the drive has already exausted it's reserve blocks,
and there is severe damage on the disk.
