Thank you, Brian.  I have tried this:

none /cygdrive cygdrive binary,posix=0,user 0 0
//?/Volume{13cb9114-4267-4a7b-8c14-2cbc4bbeecad} /media/backup ntfs noacl,binary,posix=0,user 0 0

The uid is what is shown in /proc/sys/GLOBAL??/Volume{...} and /media exists.

mount -a says:  mount: /media/backup: Invalid argument

I tried also creating an empty directory /media/backup, with the same result.

The drive sill mounts automatically on /cygdrive/d (as I would expect).

Thoughts?

Eliot
