Hmm, that's slightly disappointing. Windows knows a device type FILE_DEVICE_VIRTUAL_DISK, which I'd expected is used for ram disks. But all local non-CD file systems seem to use FILE_DEVICE_DISK. Well, that's obviously easier for testing, but still... Can you change the source and see what you get when the native NT filename is only \??\X: instead of \??\X:\ (no trailing backslash)?
