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)?
