Does this mean that having write caching enabled is not safe if you are using ext3 on an IDE drive? Should "hdparm -W 0 /dev/hda" be used for example. (I see a 50% performance hit using "-W 0" when my box is under load.) If this is the case, what is the root cause? Do IDE drives reorder writes when they are cached?

Thank you in advance for any guidance.
