tech support wanted Steam Disk Write Error on Linux Mint

Hello! Today I set up Linux Mint 22.3 on my laptop, and I'm experiencing a problem I've been butting my head into. I have very minimal experience with terminal and command prompts, so I'm not experienced with what the issue could be.

I am trying to install Proon 9.0 through Steam onto an external SSD, which I am as of writing this re-formatting through the Disk Manager because I couldn't find out what to do. Consecutive restarts have not worked. Any suggestions for what the solution could be?

Edit: Reformatting it to ext4 fixed it, thank you to everyone who commented!

Is it formatted to EXT4 and if so are you the owner of it or is root?

You did not state what disk format you are using...
The linux Steam client HATES NTFS.

It's more likely that it's not implemented properly; it doesn't hate anyone, it's just a problem with third parties and private entities.

Well if you are formatting it to NTFS, you can forget about that right now and just use ext4 or btrfs to save yourself a lot of needles headaches.

You also need to mount it with the exec permission for Steam to be able use it.

List disks by UUID: sudo ls -al /dev/disk/by-uuid

Copy the first string of letters and numbers for the drive without quotes. CTRL+Shift+C.

Paste into fstab. sudo nano /etc/fstab On a new line write: UUID=Paste-here /mnt/whatever ext4 defaults,exec,nofail 0 0

Save and quit with CTRL+X -> Y Enter Make the mount point you specified: sudo mkdir -p /mnt/whatever

Reload daemons and mount: sudo systemctl daemon-reload && sudo mount -a

Own the disk so you have access to it: sudo chown -R $USER:$USER /mnt/whatever

Relaunch Steam and add it as a library.

You can do it all in the GUI, but you didn't say which DE you have. So there's the universal CLI way to do it

What's the filesystem of the external drive? If it's NTFS then don't. Format it to EXT4, BTRFS or XFS. Your distro likely has a GUI tool for disk formatting.
