but i disable lines mount ntfs in /etc/fstab then reboot and mount ntfs drive with file manager dolphin then mount encfs on the ntfs and work and write not error.
why not work when mount partitoins ntfs on the /etc/fstab?
do you think my lines /etc/fstab is false?
The permission you see on files on NTFS filesystems are faked. They are faked from the options used during the mount. Thus you could compare both cases by comparing the permissions as shown using e.g.
ls -l one-of-the-files-in-thefile-system
It could be that what that action does is checking what the permissions are and then try to change them into what it thinks they should be. Thus when the two cases differ, in one case it will try to change (and get the error, like you will get it when you use chmod on it), in the other case it will not try to change. But that is only guessing.
Again, the exercise is rather useless because there are no Unix/Linux permissions, nor the UID and GID of ownership on an NTFS file system. My opinion is that you deviate from my (personal, I admit) rule: “Use non-Linux file systems only for direct exchange of files with non-Linux systems”.
First, you should have replaced one-of-the-files-in-thefile-system with /run/media/think_alone/d/ (which is apparently one of the files in that file system), not added that to my example statement with filler!
And to know what to do to fake user think_alone as the owner UID and group users as the faked GID read the man page:
man 8 mount
You will e.g. find there that the using both the mount options user and users is confusing. Use only one of them.
You will also find under the FILESYSTEM SPECIFIC MOUNT OPTIONS and then Mount options for ntfs:
uid=value, gid=value and umask=value
Set the file permission on the filesystem. The umask value is given in octal. By default, the files are owned by root and not readable by somebody else.
The uid= is missing in your fstab entry.
What you could have done also is looking at how the desktop mount is done (after all, you want to do more or less the same):
mount | grep think_alone
and then of course not copy the options thoughtless, but taking them as suggestions.
BTW, mounting yourself inside /media is not advisable. That is reserved for the mounting through the desktop. Mounting can be done in every suitable place (and when it is to be accessable only for think_alone, that could be somewhere in the home directory of think_alone), or, when your imagination fails here, us a mountpoint inside /mnt. /mnt is there for such things.
