Well, that's interesting. I suppose I can't count on the filesystem as much as I thought. Are you implying that the filesystems aren't ready on 64-bit? Is it more of a hardware issue (a controller lying about the security of the write)? Any comments on FreeBSD/UFS+SU? I would expect UFS+SU to have similar issues, since it depends on write ordering also. What do you do for better data security (aside from the obvious "don't pull cables")?
