> Suggestion that we document a recommendation that Windows Write Caching be
> disabled on machines using Derby.
> The following article warns about Write Caching on Windows as a possbile
> source of database corruption:
> http://support.microsoft.com/kb/281672
> It is possible that this could be the cause of some unexplained Derby
> corruptions identified after power failure of other system interupt.
> Links explaining how to disable Write Caching:
> Win 2K: http://support.microsoft.com/kb/259716
> Win 2008: http://support.microsoft.com/kb/324805
> From the Windows 2008 article:
> With some third-party programs, disk write caching has to be turned on or
> off. Additionally, turning disk write caching on may increase operating
> system performance; however, it may also result in the loss of information if
> a power failure, equipment failure, or software failure occurs. This article
> describes how to turn disk write caching on or off.
