Ok So I finally had time to try and sort this out .
So I go into Mageia Control Centre - local disks - manage disk partitions .
When finished, answer "Yes" when it asks to change fstab.
When finished doing what?
I select my harddrive that I want to be automounted without admin password .I toggle expert mode and see quite a few options.There is a tb for mount point which brings up more options . And there is another option tab whcih brings up more options .I've tried clicking the option tab and then selecting 'ticking' allow an ordinary user to mount the filesystem ' .
But nothing changers and when I go back to this option it's been unselected .
When finished, answer "Yes" when it asks to change fstab.
What is it I am meant to be selecting in the MCC in order to be asked this?
