OK, but just to make sure: The following FAQ entry refers only to *newly* created files - right? http://oss.sgi.com/projects/xfs/faq.html#nulls > Improperly written applications and/or improperly configured systems > might have issues with recently written files losing data. Again, just to make sure that I understood you correctly: Could you name an example? > Be sure the read the FAQ, especially the section about write cache on > dekstop/consumer HDDs. You are probably referring to the following entry. I now disabled the write cache of the 2nd HDD in Windows (remember my configuration). I wonder though: Wouldn't it be possible to design journaling in a way so that the write cache does never cause problems? Could someone provide an example which illustrates the write cache problem in simple terms? http://oss.sgi.com/projects/xfs/faq.html#wcache > Just my opinion as an XFS user, your mileage might vary.
