RN312 NTFS-formatted external USB drive set mount group permissions

Hi,

 

I am currently trying to change the default mount permissions for an external USB hard drive that is formatted with NTFS.

 

It mounts by default as u=root, g=root but I would like to change this to g=admin.

 

If I umount and mount via the CLI, I can achieve this but I cannot find the config file/script to make this happen automatically/via automount.

 

Can anyone assist?

 

Thanks,

 

Pierre
