It might also be that the blocksize of the filesystem matters. 4kB filesystems are fundamentally simpler than 1kB filesystems, for example. You can tell at least with "/sbin/dumpe2fs -h /dev/..." or something. Andrei - one thing that might be interesting to see: when corruption occurs, can you get the corrupted file somehow? And compare it with a known-good copy to see what the corruption looks like?
