It seems that NT probably does the same thing - if you happen to have an
OS/2 HPFS partition (id #9), then NT thinks it is an NTFS partition(id #9).
If you are unlucky, then this partition will be in such a place that it is
assigned drive letter C. NT will then get confused as it can't actually
understand what's on C:  God, I *love* mount points - and I *loathe*, *hate*,
*despise* drive letters :-)
