Mounting drives using HAL in Ubuntu

Some drives in Ubuntu are mounted using HAL. To change the mount options for these drives, do the following -

• Run gnome-mount -u -d /dev/sdb1.
• Run gnome-mount -d /dev/sdb1 --display-settings to view current settings.
• Run gnome-mount -d /dev/sdb1 --write-settings --mount-options umask=000,opt2,opt3=foo to set the mount options. 
• If you want to keep the existing options and change/add only a few, then use gnome-mount -d /dev/sdb1 --write-settings --extra-mount-options opt4,opt5=foo.
• Now mount the drive in the usual way (from Nautilus).

To see complete details about the drives mounted by HAL, run lshal.

(In the /dev/sdb2 example above, remember that umask=000 gives everyone all permissions; so it is the inverse of what you would give for chmod.)
