How to mount partition permanently?
Unmount is greyed out because the partition isn't there to be unmounted. You haven't mounted it yet.
To make the partition auto-mount, first find out the UUID of /dev/sda3 by doing:
sudo blkid
I'll assume you're using ext4 on /dev/sda3. Open up gedit
like so:
sudo -H gedit /etc/fstab
(Or, in the command line, sudo vim
or sudo nano
instead of gksudo gedit
.)
Now you want to add a line to the bottom of that file. It should look something like this (UUID will be different):
UUID=03ec5dd3-45c0-4f95-a363-61ff321a09ff /media/works ext4 defaults 0 2
For more info on fstab
, this is a good resource.
Use Disks utility. Select the disk, then click Additional partition options. Choose Edit Mount Options from drop-down menu.
