That story is in the news today. http://www.h-online.com/open/features/Linux-and-Windows-8-Fast-Startup-puts-data-at-risk-1780640.html There are few official patches for NTFS-3G driver, you might want to apply them now because the next release is not ready yet. Redhat have done that: https://bugzilla.redhat.com/show_bug.cgi?id=859373
I committed sys-fs/ntfs3g-2013.01.13 yesterday that includes those fixes. If you would like it stabilized, please file a stabilization bug.
