Restrict access from another user to the NTFS partition

It is possible somehow restrict access to a partition to a specific user in Ubuntu? I am using Ubuntu x64 11.10, I made 2 accounts, both accounts belong to the Administrators group. And I have 3 partitions, on first is OS formatted in ext4, the second one is swap, and the third one is partition designed for data storage, formatted in NTFS, now I want to restrict access to the third one for second user, or hide it. And by the way, the NTFS partition is set to mount automatically at start up.

Solution 1:

Create a group called ntfs. Then edit the group to add all of the users that you want to be able to access the ntfs partition.

sudo addgroup <groupname> ( ntfs )

Then

    sudo chgrp ntfs /media/disk (ntfs )
    sudo chmod 770 /media/disk (ntfs )

To add a new user to a existing group you would do this:

sudo adduser  (username)  ntfs
