If you aren't comfortable using cli, then both kde and gnome can do this for you.
I believe that it is under the "Users and Groups" menu selection on both, but not sure.
If you want to do it the cli way, then you would (as root):
Code:
#groupadd foo
#chown root:foo /mnt/maxtor
#chmod 770 /mnt/maxtor
#
#usermod -G <comma separated group list> <user id> (you can manually edit /etc/groups to
add your user to the group instead of using usermod, because using usermod, you will have to
list all groups that the user is a member of as it is an absolute list, not an append-to.
If you leave out a group, that member will be taken out of the group you leave out.
Here is a link that will help you:

The link will explain everything to you.
It will be a lot easier if you want to use the gui, as you can just click on the group, and click edit, and add your user.
