I have a number of drives internal and external. Some are partitioned. Most mount automatically at boot (all did at one point).
One partition is owned by root and therefore does not mount automatically. I know how to mount it as root.
I do not know how to take ownership of that partition as user X. I have tried changing permissions using the gui in Nautilus as root. They are not accepted and immediately revert.
The partition is NTFS. The other parition on that drive is owned by me as user and mounts automatically
