USB stick automounts as root instead of user

[mgruber]

I'm using Mint XFCE 20.3.
I own several USB sticks, most are FAT32 or NTFS formatted.
Now I got a new USB stick, which I re-formatted using EXT3 (the target device it's intended doesn't support EXT4).
XFCE automounts this stick now using root rights, so I'm not able to use it as normal user without manual re-mounting.

How can I fix this?
All my other USB sticks automount with user rights without any problems.

You created the partition with root privilege so root owns the partition.
You will need to change the owner and group to your username.

Find the mountpoint. It should be /media/username. If the partition is labeled it will show as that name.

Then:
chown -R $USER:$USER /media/username/label or id
substitute your username after /media/

In this example the command would be:
sudo chown -R $USER:$USER /media/uno/90B8-260E

What did you use to reformat? Gparted? If so, next time try Disks to reformat.
I think it will be owned by you if you use Disks.

Yes, I used Gparted.
Thank you for the explanation, solution and how to prevent it in the future!
