The issue here is that you have mounted the partition to your mount point as root which means only root can manipulate it. Without user permissions set in fstab, users can not change the content even if you set the right permissions on the mount point itself.
With the user permissions set in fstab, you can. However, if you can dump files directly onto a mounted partition; so can others.
What I do to get around this is create a directory /mnt/data/ which has the same name as my username. This way I can share the partition with other users without revealing any of my data as they will have no access to my directory on that partition.
If you feel that navigating to /mnt/data/youruser is a hassle in order to get to your files, all you have to do is make a symbolic link to the /mnt/data/youruser in your home directory.
As a regular user, do the following:
Code:
sudo mkdir /mnt/data/myusername
sudo chown myusername:users /mnt/data/myusername
ln -s /mnt/data/myusername ~/data
If you take a look at your home directory, there should now be a symbolic link named "data" which will take you to /mnt/data/yourusername. The best part is that it will act as a regular directory inside your home directory.
Hope this helps.
Cheers.
