I'm using ntfs-fuse to mount a volume (rw) in fstab.
Nautilus displays the device, but when trying to open it, pmount says the device is already mounted according to fstab. (some other user reported that mount, instead of pmount, is giving this error).
The system seems to be trying to mount an already mounted device.
Actually, the experience with this so far has been a bit flaky, since the drive will show in Nautilus/Computer but not in the Places tab. And it's not everytime that it shows under Computer either. For example, I just included the locale=pt_BR.UTF8 in the fstab mount options, and upon reboot, Nautilus doesn't lists the drive anymore at all.
Excerpt of my fstab file:
/dev/hda1 /media/Aalto ntfs-fuse auto,gid=114,umask=0007,locale=pt_BR.UTF-8 0 0
