I know NTFS is still somewhat in its > infancy. if its mounted as a block device, nothing else should touch it, read OR write. block devices are NOT sharable, with the exception of specialized filesystems like GFS or IBrix Fusion Even a read only access would have issues with metadata consistency, if windows is updating a directory or MFT or whatever, linux could see stale/mixed data and would just throw up the only 'safe' way to do it would be for the windows machine to share the logical file system, and have the linux system access it as a smbmount via samba. or use replication running on the windows server (rsync from mingw, etc) Windows 2003 server has its own snapshotting capabilities, btw.
