I discovered I was wrong about having full read/write access when accessing the “Liam’s Gameplay” drive by first mounting it manually in the command-line. I actually don’t have access at all; root does.
This is almost the same as what happened yesterday when I was asking for help in these forums with getting permission access to my other hard drive “Linux Storage”. The solution to that was to mass change the ownership of all the files on the drive by using the command sudo chown -R yourusername /media/yourusername/mountpoint
This completely solved my problem with not being able to do things with the data on my “Linux Storage” HDD.
Shouldn’t the same command work on “Liam’s Gameplay” to regain my ownership and permissions of the files on the HDD? Is it safe to execute?
If “Liam’s Gameplay” being owned by root isn’t the thing causing the mounting issues, it’s at least a major problem in itself, since I can’t write or delete any files on the drive unless I give ownership back to myself.
