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)).
