That should be possible with an fstab entry.


Here is a full example fstab entry:

/dev/sda1 /windisk ntfs nouser,uid=0,gid=0,umask=002 0 0

assuming sda1 is your ntfs partition,
/windisk is the mount point where it should appear (root must have created this directory in advance)
umask=002 means read only for the world, r/w for the owner (root) and group (root)

You don't have to reboot to test it: run the command 'mount /windisk' as root


If you don't want the world to read /windisk, then use a group membership.

/dev/sda1 /windisk ntfs nouser,uid=0,gid=46,umask=027 0 0

Put the special user Knoppix into the selected group (46 in the example, can be anything)
# adduser knoppix 46

Now, root has r/w, and anyone in the group 46 has r/o access. You control who is in that group. It could be 1 user only.
