Erm, is the hardware problem really as great as you're implying?
Have you personally encountered any bad drives made by reputable
brands? Mostly I've only heard only of people crying wolf and then
realizing it was a problem with their reasoning or with the
assumption that fsync() actually works properly on kernel X, where
X doesn't even have to be that ancient a version of linux ;-)
No, I've seen several sample cases on this list of drives where the
IDE or SCSI cache flush commands did not trigger any disk activity
and the only way to force it out of the cache was to write several
meg of garbage to some file. In some cases (Like RAID cards with
good battery backup, for example), they may ignore the flush cache
command as it isn't really useful (although on such good cards, they
usually haw a way to turn it off, too).
