Kindly offline I hear we might find more folk interested in how reliably Win flushes

        Kindly offline now I hear Win 2K/ XP do at least sometimes send Ata flush & 
Atapi sync cache to writeable disks before hibernate/ suspend.

        
        I can't easily reconcile the idea of any particular kind of Win always sending 
those commands with my memory of bus traces that show no errors in Win talking to 
devices that do not write-behind and correspondingly reject flush/sync commands.

        
        Possibly Win plug 'n play somehow magically concludes whether a device 
supports flush/sync or not. 
          
        Possibly only my memory is at fault, or only the Win 98SE/ ME now being 
obsoleted, or the already obsolete Win 95/ 98/ NT 4.  When Win first offered suspend, 
when Win first offered hibernate, I do not remember.  I hear the Win offering could be 
out of sync with the Bios offering.  I specifically remember seeing hosts choosing to 
suspend at times when BSY=0, no matter that DRQ=1 ... possibly only Bios/ Dos/ Win 95 
hosts, not later Win.
