This is the same goal as journalisation, just a different=20 method. However, any data not fully commited to disk is forever lost. I guess=20 this applies to unsaved documents. Note that the hard disk's write cache should be __disabled__ or there's=20= no point in using softupdates at all. Up to now, there's no support for=20= "safe write cache" operation. To my knowledge, it only exists in=20 windows 2000 sp3 and xp.
