It would be interesting if anyone could explain the reasons why ufs/ffs and zfs  and FreeBSD are not effected by this issue .  My rudimentary understanding of the issue was that it's wasn't just a software glitch in the ext filesystem and bad firmware but a combination of that and Linux poorly supporting a ata modes that are not supported at all on FreeBSD .  Is that correct ?
