Actually, what Thomas posted is correct.  The FAT corruption from failing to
handle media change is not a problem on hard disks (no media change events!).

On the otherhand, the sync problem Michael is talking about (and Allan was
talking about) is a delayed write problem of another colour.
Yes, if you do delayed write cacheing you are subject to loss on freezeup and
power down, or media change.

Note:  UNIX has the same problems if you pull the cord or otherwise
power down in an uncatchable manner. Ever wonder why AT&T machines don't
really turn off when you turn the switch off?  That's right sync time.
