Its well accepted that reiserfs3 has some robustness problems in the
face of physical media errors. The structure of the file system and the

managed to achieve both robustness and better data structures.
How reiser4 compares I've no idea.

I ask because your clam differs from the only detailed research that
I'm aware of on the subject[1]. In figure 2 of the iron filesystems
paper that Ext3 is show to ignore a great number of data-loss inducing
failure conditions that Reiser3 detects an panics under.
Are you sure that you aren't commenting on cases where Reiser3 alerts
the user to a critical data condition (via a panic) which leads to a
trouble report while ext3 ignores the problem which suppresses the
trouble report from the user?
