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
