Problem mounting NTFS external drive

Zetsumei · 2009-01-01 19:59:20

Been trying to get my external drive mounting my ntfs external drive in my user's ownership, not roots.

I first did sudo mount /dev/sdb1 /media/external and then sudo chown -R bryce:bryce /media/external/ and that only changed the directories ownership.

Then I edited the fstab and did mount /home/bryce/external and get this error

[bryce@arch ~]$ mount /home/bryce/external
ntfs-3g-mount: mount failed: Operation not permitted
User doesn't have privilege to mount. For more information
please see: http://ntfs-3g.org/support.html#unprivileged
[bryce@arch ~]$

Any help from you all please?

AFAIK mount will only work as root, pmount will work as regular user if the user has the necessary permissions.

EDIT: Other than that, the instruction on that wiki page always work for me http://wiki.archlinux.org/index.php/NTFS_Write_Support

If I do sudo mount /home/bryce/external then wouldn't root own it then? I'm trying to make it owned by my user.

See the wiki I linked -- it tells you what mount options to use to set particular permissions.

SOLVED: I forgot to do

sudo chmod u+s /bin/ntfs-3g

I read the wiki and added the options like it stated, here's the /etc/fstab

#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0

/dev/sdb1 /home/bryce/external ntfs-3g users,noauto,uid=1000,gid=1000 0 0

UUID=ba883d5b-fdbd-453b-8ff5-033b23decc7a /boot ext3 defaults 0 1

The error I get is

[bryce@arch ~]$ mount /home/bryce/external
ntfs-3g-mount: mount failed: Operation not permitted

Like I said -- mount has to be run as root. [EDIT: unless you manually change permissions, like you did]

This is what I have in fstab:

/dev/disk/by-label/windows  /mnt/windows    ntfs-3g     users,noauto,uid=1000,gid=100,fmask=0113,dmask=0002,locale=pl_PL.utf8   0  0

This is what my mount dir looks like when the drive isn't mounted (notice the permissions):

$ ls -la /mnt/
total 4.5K
drwxr-xr-x 8 root root 192 2008-05-13 17:06 ./
drwxr-xr-x 23 root root 552 2008-12-14 16:14 ../
drwxr-xr-x 2 root root 48 2008-02-07 18:41 windows/

And now when I mount the drive (notice the permissions again):

$ sudo mount /mnt/windows/
$ ls -la /mnt/
total 8.5K
drwxr-xr-x 8 root root 192 2008-05-13 17:06 ./
drwxr-xr-x 23 root root 552 2008-12-14 16:14 ../
drwxrwxr-x 1 filip users 4.0K 2009-01-01 15:19 windows/

So the permissions/owneship is completely independent of whether you're running mount as root or not.

See my post before yours, I did the sudo chmod u+s /bin/ntfs-3g and it worked. It's owned by my user, etc.

It's an ugly hack, and you'll have to fix the permissions manually every time pacman installs new version of ntfs-3g, but if you're happy with it...

When mounting ntfs volumes do

sudo mount -o umask=000 /dev/whatever /mountpoint

Works like a charm for me.
If it is an external drive then you should consider editing the udev/hal rules file (can't remember which one I needed to edit, check the wiki )
