At first guys, you confuse file system drivers and storage drivers. The
file system drivers have de facto no knowledge on which disk are the
data located, (on Windows) they recieve an object and send Read/Write
requests to it (well, basicly, in reality there's also the cache manager
between them). At second, the idea can't work, even if you would have a
storage driver that uses some backdoor I/O port to access host disk, the
host OS can't access the same partition at the same time due to things
like caching (on both sides (guest/host)).
