Well then perhaps they would care to share the information with us 8)

The HPA size reporting one is certinly Linux, the flush cache one I don't
think is. The fact Mac people report it and Seagate suggest workarounds
of the form of "don't use 33% of the disk" don't inspire confidence.

Well if they'd care to explain it to linux-ide perhaps we can find a work
around. I would be cautious about disabling the write caching as it will
harm both performance and probably drive lifetime.
