“Whoops now it’s uneven better have another”

Excellent news! Hopefully this sends you smoothly on your Jellyfin jouney.

Then I think potentiallynotfelix is on the correct path. Apologies if I’m diving in too basic for you. Just to check whether you have it mounted or not if you open a terminal and cd to your media folder cd /media/RVAtom then ls -l it should list what is there. If it has been mounted before you should see SSD among the items.

If it is among the items to check if it is mounted from the ablve point you should be able to cd SSD and then ls -l again and see your contents if everything should be good to go.

As an aside, since this is a new drive do you know what type or partition, if any, exists on your SSD? You can see this in the disks app I believe.

Edit: attempting to properly wrap command snippets

Are you running Jellyfin in a Docker container?
