  Was the partition created and/or formatted from the Linux side, using
ntfstools for example, before windows was installed to it?  Or did you use the
format option in the windows installer?

  Cygwin doesn't use raw block I/O to write corrupted disk block structures to
your HD, that's for sure.  But one thing it does do that's a bit unusual is to
create a hell of a lot of ACLs, compared to a standard windows installation
where most stuff doesn't have a custom ACL and just inherits from the
directory tree.  I wonder if for some reason this drive got formatted in a
funny way that didn't leave enough room for entries in the security descriptor
database special files?

    cheers,
