HowTo automount external ntfs-formatted USB hard drives with write permissions for normal users AND the correct locale...

To automount your hard drive with write permissions, first backup your fstab.

su
cp /etc/fstab /etc/fstab.bak

Then plug in your drive and give it write permissions in ntfs-config. This puts and entry in fstab, which effectively prevents HAL from automounting the drive. So you need to replace the new fstab with your backup. Then unmount your drive.

cp /etc/fstab.bak /etc/fstab
umount /dev/sdXY

If you now try to mount your drive in Konqueror with right-click --> Mount, it should give you an error message. Now edit your /etc/PolicyKit/PolicyKit.conf and put in any users or UIDs who need to be able to mount the drive.
<config version="0.1">
<match action="hal-storage-mount-removable-*">
<match user="taaris|1001">
<return result="yes">
</return>
</match></match>

Then reload the settings.

polkit-reload-config

If you now plug in your drive or mount it in Konqueror, it should be mounted with read/write permission for everyone.


To mount it (and everything else you mount with ntfs-3g as well) with the correct locale, you need to replace /sbin/mount.ntfs-3g with a small bash script.

su
mv /sbin/mount.ntfs-3g /sbin/mount.ntfs-3g.bak
touch /sbin/mount.ntfs-3g
echo '#!/bin/bash
/bin/ntfs-3g -o locale=de_DE.UTF-8 $1 $2' > /sbin/mount.ntfs-3g
chmod +x /sbin/mount.ntfs-3g

Just one little annotation... by echoing as taaris suggests, you echo into the destination of the symlink and overwrite your ntfs-3g binary.
Better do:
rm /sbin/mount.ntfs-3g
and create a new file with vi filling in her nice script.

Changed "cp" to "mv" so that people don't accidentally end up echoing into symlinks....

On my system it's /usr/bin/ntfs-3g so change that in mount.ntfs-3g if necessary

The following version of the script allows spaces in the label of partions and passes other options to ntfs-3g (via the $4):

#!/bin/bash
/bin/ntfs-3g $1 "$2" -o locale=en_US.UTF-8,$4 #put your own locale here
