I have a ntfs partition and when I mount it with default options in fstab I get for files and directories: rwxrwxrwx = 0777 Obviously ntfs does not support "noexec" option and I do not want 'x' flag to the files and directories. So I'd like to ask what values shall I set to fmask, dmask and umask? When I set umask=0666 /dev/sda3 /ntfsPartition ntfs-3g defaults,noatime,umask=0666,locale=en_US.utf8,errors=ro 0 0 I get d--x--x--x for the mount directory of the partition. I can go the directory: cd /ntfsPartition but I cannot read the content: ls /ntfsPartition ls: cannot open directory '.': Permission denied Thanks in advance!
