Confused over device ownership - SOLVED

[bushyiii]

Using lM 20.2 Xfce.
computer:/// lists all my devices.
Checking properties / permissions shows HDD ownership as "root:root "
In the terminal using "ls -la" shows device ownership "guy:guy"
I have Plex mediaserver that so far is unable to access the files on all the attached HDDs that display the same properties as listed above.
File permissions for the media drives is 777

Any guidance is greatly appreciated.

In the terminal using ls -la shows device ownership "guy:guy"

by default the ls commands refer to /home/username---so yes it is showing guy:guy for files and directories
in your home directory--it's your directory and you own the files-all is peachy here.
If you open the terminal in a specified directory and run ls -la the results are displayed for that specific directory.
see terminal results of:
man ls

Also please post the terminal results of the following:

Code: Select all

lsblk

Code: Select all

blkid

and:

Code: Select all

cat /etc/fstab

Any guidance is greatly appreciated.

You should post the exact commands you issued and the responses that Mint/bash/whatever issued, inside </> "code" tags, like this:

Code: Select all

$ ls *.not
ls: cannot access '*.not': No such file or directory

The ls -la command had been executed within the attached usb drive: "guy@guy-HP-Compaq-8200-Elite-SFF-PC:/media/guy/7Tb$ ls -la"

Code: Select all

guy@guy-HP-Compaq-8200-Elite-SFF-PC:~$ lsblk

The picture url is composed of three screenshots adjacent to one another. From left to right the 1st is a shot of "computer:///", 2nd is the Permissions tab for "Seagate Backup+ Hub BK: 7Tb" showing "root" as owner & the 3rd showing the terminal output of "/media/guy/7Tb$ ls -la"

I just noticed something from the beginning of the ls -la output that had scrolled off the window.

Code: Select all

guy@guy-HP-Compaq-8200-Elite-SFF-PC:/media/guy/7Tb$ ls -la

Devices belong to root.
Partitions created in Linux belong to root.
Users can take ownership of the partition mountpoint--but the partition is still
owned by root.

Thanks, I was unaware, I thought the user that created them could own them.

Yes--only root can create partitions, so newly created partitions automatially belong to root.
You can gain read/write if you take ownership of the partition's mountpoint.
